I took a morning after pill in February 12 hours after unprotected intercourse. I got the week later bleeding for about 5 days. Then I got a period in March that lasted 6-7 days which was super heavy and had lots of clots in it. Now it's April and I have no sign of my period. My boobs hurt so bad and have become huge. I have no discharge at all. NOTHING. my underwear is perfectly clean day in and day out. I have taken 4 home pregnancy tests and 1 doctors urine test throughout February to just last weekend (April). They all came back negative. if I was pregnant I would be 11 weeks. I'm so confused. Can anyone help?
