15 DPO: most common pregnancy symptoms
If you have a regular menstrual cycle and get your period about every 28 days, you will probably miss your first period around 15 to 17 DPO if you’re pregnant. For most people, missing their period is the first big symptom of pregnancy.
The beginning of your pregnancy will be counted from the first day of your last period. If you have a regular cycle, that means that you’ll be four weeks pregnant by the time you miss your period.
Home pregnancy tests work by detecting the levels of a hormone called human chorionic gonadotropin (hCG) in your urine. As your pregnancy progresses, the levels of hCG in your urine will rise (you can use our online hCG calculator to track your levels if you get a positive result). That’s why some people get a negative test result even when they are pregnant (a “false negative”). A false negative can happen if you take the test too early, before the level of hCG is high enough to show clear results.
You probably won’t experience many pregnancy symptoms at 15 DPO. There is, however, a symptom of pregnancy that you might have already experienced by 15 DPO: implantation bleeding. Although not everyone experiences implantation bleeding, if it does occur, it’s one of the earliest signs of pregnancy. Implantation bleeding happens when a fertilized egg travels down to your uterus and burrows into your uterine lining. This process is called implantation, and it can cause some mild bleeding.
