I had sex for the first time on may 15 , 16 and 18th. I got my last period on may 3rd. I have a small cycle of usually 2.3 to 3 weeks, so I was expecting mine on 24 or 25th. but I have still not received mine.

we used male condoms. and also one thing was wierd that I had sever low back pain on 20 and 21st that I had to midol to get to bed.

am I pregnant? or am I late because it was my first time? also.. usually I would PMS real bad and get into all kinds of arguments, but not this time..

please help..

My best friend works in a doctor's office and she told me that sex messes up your cycle. It happens to me. My bf and I stopped having sex to be safe from me becoming pregant because I had a few scares. After we stopped it came back every month like clock work. I hope that helps

If you had sex - be it first timre sex or not - even with a condom and you miss your cycle instead of driving yourself crazy about the question of being pg you need to see doctor
