I am 15 years old. I know i'm way too young to be having sex. Especially unprotected sex. But sadly i did. Unfortunately I've had a lot of unprotected sex. My period is always regular. It always came on the 1st of the month. But I missed my period for april and it's passed the 1st for May and it still didn't come yet. I've taken a pregnancy test almost every week and I just took another one about 30 minutes ago. and it came out negative. I'm very confused on why the test isn't saying i'm pregnant if my period isn't coming. I've looked on dozens of websites to see what some people may say. But the most that I saw was that some women had the same issues but then they became pregnant about 2-3 weeks after their first missed period so I got confused all over again. Does anyone who are maybe in or been through the same situation know what I should do? One comment told me I should go to the doctor and take a blood test...
