Im really worried I might be pregnant. My period is three days late. 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 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 also. Please help!!!
