HI, After taking meprate on january 2nd I got my periods .on 4th day of my periods I had some dry sex with my bf. Im with only underwear within pads and my bf with his only boxer. I noticed some days of him touched my underwear. Later 10 days after completion of periods I observed light brown discharge and later again white discharge .again I have taken meprate for periods .i got periods on february 5th .after completion of periods I had taken home pregnancy test .it showed negative .now it's been a week after periods .i have been observing light spotting. Does this mean I am pregnant or is it side effect of taking meprate? I'm very much tensed please answer.
