I've been trying to conceive for a few months now, I stopped Depo-Provera at the beginning of August & switched to Ortho-cyclen birth control pills but Im not longer taking them, I've only had one period since stopping birth control Aug. 29,2013 & I had intercourse Sept. 28, 2013. I believe Im having Implantation Bleeding for about 4 days, its not heavy like a period, mostly dark brown discharge early today it changed colors from brown to dark brown to dark red & now dark brown again the bleeding was very light & mostly came out only when I wiped & now its almost gone. If I am pregnant am 3 weeks & 4 days. Im a right that this is Implantation bleeding & not a period.?
