Hi i am 18! I had started my birth control 5 days after i ovulated, as instructed by my doctor, and then i had to stop a couple of days before i was supposed to ovulate. My fiancée and i are wondering if i could have fallen pregnant seeing as we have been having a lot of unprotected sex. I have been very tired lately, my boyfriend complains that i am really moody, i have the urge to eat all the time now but little meals, and i have a strange craving for M&Ms. I have been bloated for the past week and i was expecting my period but as of today its 4 days late, my cycles are very regular, i can tell down to the minute when i should get my period, but this month it hasn't come. I have on and off constipation. My breasts feel heavy and my nipples have gotten darker and larger in the last three days. Should i take a pregnancy test or just wait if my period comes??
