Hi, I had unprotected sex on the 11th of March (17th day of cycle) and took emergency contraceptive pill 18 hours later (Estinor- 2 pills). 10 days after that, I tested negative and I started to have brown/bloody discharge on the 24th March (29th day of cycle) which became heavier bleeding days after and lasted for 7 days. Very much like my period I would say- blood red and with clots. But my cycle is usually 30 to 35 days.

I keep feeling dizzy and nausea-tic these days but I tested negative on the 29th of March- 18 days after the unprotected sex. Is 18 days too early for the test? Could I be pregnant?
