Ok, so i ended my period probably the 2nd of Feb., I want to get pregnant so just recently I've stopped taking my pill. I stopped taking it probably around the 6th, I just had unprotected sex saturday (9th) sun & monday. I didn't have sex on my period, but i did the weekend before it. I had a terrible headache all weekend long, and now, tuesday morning, I had brown on my underwear and it looks like it would normally look right before I go to start my period. I have been stressed lately, but last week I was nauestaed for about 2 days, never puked but felt like i was gonna, i've been really hot at night lately too. And I haven't been going to the bathroom regularly either. He hasn't went inside of me though. Could I be pregnant?
