So I've been off of birth control for a couple months now, the hormones from the pill was making me sick so I voluntarily decided to take some time off of them. Since being off the pill my fiance and I have had unprotected sex. I was pretty regular with my monthly visit from aunt flow, always starting the day I was suppose to or the after. Well this month I was 4 days late, then I had 2 days of light flow, then one day of nothing followed by some disharge with a little blood in it the next night. Now, still no regular period, I usually go for 5 days (always 5 days since I hit puberty) this is very abnormal for me. I had a week and a half of cramping along with a week of nausea before the 2 days of bleeding happened. Since those 2 days I havent had any cramping but the nausea has lingered. I've taken pregnancy tests but all negative, I'm just confused as to what is going on. Any advice?
