So, for starters Last month I never got a period, rather then a period I had three days of immensely light spotting. Around February 17-20th. (I cent exactly remember) either way, it didn't worry me too much because I have an irregular period, although I am sexually active. In the past two months I've been off birth control and having sex unprotected. (Bad choice I know.) but, I've done it multiple times before and never gotten pregnant, shockingly. Yet it's no excuse. Anyways, this past week, my body has been off and my breast have been swollen so badly, to the point that my nipples have doubled in size. It's super painful and I beloved it might've been a sign of pregnancy. Ive also been quite sick on and off. For example; I woke up out of a dead sleep in major pain and cold sweats around 3 am one night. My stomach was so upset to the point where I couldn't move, I laid in bed in pain and sickness for over an hours before I began puking my guts out. This has happened a few times, usually Early in the morning from 2am to 10am.  I've taken plan B pills just in case after intercorse etc. But I'm still curious to the cause. At this point I'm late on my period this month and still never received one between now and my last spotting time (feb 17-20th ish) it's now march 22nd. I've taken a few expensive clear blue pregnancy tests within the past 3-5 days and all are negative, can anyone give any advice? Also if it counts for anything or connects to any if these issues, I've broken out in horrible rash and hives in the past week and a half as well from unknown causes, could that be linked to any of this? Your advice is super appreciated! Thanks!
