Hello, This might get a little lengthy... I don't keep track of my period but my last period started on March 24th and it usually lasts 5 days with the last two days being very light. The last time I had sex was on April 5th. We had sex twice that night, once with a flavored condom that was maybe 2 years old and once with a normal condom. One of those times he ejaculated twice without pulling out and changing condoms. That being said...fast forward...this last Saturday, April 22nd I spotted mid day. There was a tiny drop on my underwear and very light pink when I wiped. I inserted a tampon thinking my period had started and when I took it out a few hours later there was absolutely nothing on it. I kinda freaked and took a pregnancy test and it was negative. It's now Monday evening and still no period. I took another pregnancy test at work today that i bought at dollar tree and it was also negative. And so...is there any chance that was implamentaion bleeding?
