My protection failed on 28th Feb, and i got withdrawal bleeding for 4 days on march 6. Then, i had protected intercourse on 16-17 March (fertile days) and then got spotting for 1 day and 2 days of full period on 2nd April till 5th April.. Though light.
My period was due on 1st may. It hasn't come yet 2 days late. I have done home
pregnancy test and it came out to be negative 4 times.. What could be possible issue?
