my boyfriend and i have had sex unprotected only 3 times so far in the last month. My situation is complicated though, i have a VERY irregular periods. Maybe 2 per year. Ive asked doctors and they say that i am fine, and that its normal, which i think theyre crazy. i havent had a period in about 6 months, and i had unprotected sex on the 4th and the 5th of november, and about on the 10th, i started bleeding VERY dark brown blood. for about 3 days or so. Its the 1st of December today, and ive been pretty nauseated for the last 5 days or so, sometimes the nausea comes in waves, like only after i eat or drink, my nipples are terribly sore,my breasts feel heavy, i have been thirsting for water like crazy. i also cant sleep more than 8 hours in the night. But i am terribly tired all day. i took a pregnancy test about 2 or 3 days ago, but i got a negative. My symptoms keep getting stronger and I am wanting a baby badly and i am worried that because i dont have a regular cycle, it will be difficult for me. Im also worried that its all in my head, and im wanting to be pregnant so badly that i am psyching myself into it. Were not necesserily "trying" but i would jump for joy if i got pregnant. Any advice would be great, thank you!
