My last period date was 9/02. My expected period date was 11/03. I had primolut n on 6,7,8th march. My period date was 11/03. However even after stopping pills I was on periods even on 13th. We are planning a 2nd baby. We had unprotected sex on 13th and 15th. I am yet not on my periods. Does that mean that I am pregnant. I had urine lab test on 15th which was negative. Was it too early to take the test.
