My last REAL period was August 14. It last about 5 days and was really heavy from the first day. My periods are pretty regular and I have been having sex for about 3 months now - 2 months of it protected, 1 unprotected. I have been getting my periods as expected every month just different date, but this month I didn't - not really. (I'm not stressed or worried, just curious- so that can't be why I'm not having a real period and I have already had a period before, my body is used to the sex-so that can't it either.) I had unprotected sex on the 5th and he came in me, and every time since then, but on the 9th I spotted and other pregnancy symptoms have sprouted up. I took 3 test so far, spread out over the past week and all were negative. Tuesday will make 20 days since I had sex the first time which is when I think I might have conceived - if I did. Can I be pregnant?
