My boyfriend and i had unprotected sex just a day after my periods so he told me to take the first p2 pill at 16:20 so we had to take another pill at 4:20 am but we overslept we realised it when it was 9 am in the morning.. I panicked and i remembered i read the leaflet that its exactly 12 hours so he rushed and bought another pill of p2 and i took the 2 of them at the same time... After 8 days i bled heavily for 3 days....now my period is late by 3 days could i be pregnant please
