The signs of pregnancy after sex can be confusing. Maybe you’ve had unprotected intercourse, you’ve missed your period, have some breast pain, or you just feel off. We get it. Conception and fertility aren’t always straightforward. Knowing a little more about them can help you understand pregnancy.
Let’s have a chat about something important – the process of becoming pregnant. We know it might be a lot to take in right now, but let’s take it step by step.
Your fertility cycle
So you might have heard about how our bodies work in cycles.
Your period comes in a rhythm, called a menstrual cycle. Cycles aren’t the same for everyone — your cycle might be the same every month or slightly irregular. There’s a big range of what’s considered normal.1
Every month, an egg is released from your ovary (if you experience typical fertility patterns). This happens during ovulation, which occurs between your monthly periods. If the egg isn’t met by a sperm, the egg is broken down and you have your period.1
However, the egg can connect with a sperm if they’re together at the right time. If you’re wondering about the signs of pregnancy after sex, it might be because you’ve had unprotected sex. Having sex can lead to sperm entering your body and meeting with one of your eggs.2
When this happens, there’s a chance that the sperm can fertilize the egg, and you can become pregnant.
How long does it take to find out?
After you have sex, it might take a little while to find out if you’re pregnant. Even if the egg and sperm meet, it takes some time for your body to produce enough pregnancy hormones for a pregnancy test to detect.3 So, if you take a pregnancy test too early, it might not show accurate results. Pregnancy tests can bring up anxiety and strong emotions, especially if you’re getting mixed results. It’s best to look for a sign of pregnancy; wait until after you miss your period before taking a pregnancy test.3 If you decide to take a pregnancy test from the store, make sure to read the directions on the best time to take the test. Or you can call us at ThriVe to speak to someone who can help you determine when to take a test and/or make an appointment with one of our nurses.
Taking a pregnancy test can feel scary to some people. Having an ultrasound can actually confirm if you’re pregnant or not — even early in a pregnancy.
If you’d like someone to be with you for your pregnancy test, our team of nurses at Thrive+ would be happy to support you for that. You can talk about the symptoms of pregnancy after sex and learn about the resources available to you. Call us for a lab-quality, no-cost pregnancy test.
Pregnancy symptoms after sex: bleeding
Sometimes, after sex, a person might experience some bleeding. This can happen because the tissues are sensitive and might get a little irritated.4 However, if you’re experiencing a lot of bleeding that continues, you should see your doctor.
There’s something called implantation bleeding, which is a bit different. This bleeding can sometimes happen when a fertilized egg attaches itself to the lining of the uterus,4 some spotting might occur. Bleeding from implantation doesn’t always happen, and doesn’t happen right away after sex. It usually happens 10-14 days after sex, but can vary from person to person. It’s usually lighter than a regular period and doesn’t last as long. It doesn’t mean you’re having a medical emergency, but it’s a good idea to make an appointment and talk to a nurse.5
Speaking of periods, let’s talk about them too. Period bleeding is the normal shedding of the uterus lining.1 It’s different from implantation bleeding because it’s usually heavier and lasts for a few days. But if you’re unsure, taking a pregnancy test can help clear things up. Contact your doctor anytime you experience vaginal bleeding which is not normal for you.
Early symptoms of pregnancy
Now, about early pregnancy symptoms after sex – they can be quite different for each person. Like we mentioned, a missed period is the big one, but there are other symptoms too, like hormonal changes. Some women might start feeling a bit more tired than usual. You might start to experience nausea or vomiting after a few weeks. That’s referred to as “morning sickness,” but it can happen at any time. Many women start to notice changes in their breast. They might become tender or sore.6
You may notice some mild cramping, kind of like period cramps, but different. These symptoms can show up in early pregnancy.6 If you start having intense pain, see your doctor to make sure you aren’t having a medical emergency. Keep in mind that having only one of these symptoms doesn’t necessarily mean you’re pregnant.
Everyone’s body is unique. These signs might not be the same for you.1 If you think you might be pregnant or have any concerns, it’s always a good idea to talk to a doctor. They’re experts and can provide the best advice based on your situation.
