Saturday, sunday, and i think monday i took the maximum number of advil. I was suppose to get my period wednesday but I never got it. Today is now saturday and according to my calender im 3 days late even though my period is irregular. Some are 37 days some are 41. Never 28. My last period was May 12-17. I have been sexually active since then and I am so worried that there is a possibility I might be pregnant. I was sexually active on the 18, 29, and 5. I am not on birth control but my boyfriend and i ALWAYS use condoms. I have been having this white discharge tho. Please help!!!
