I recently had a smear came back negative which is good. My cycle is 24days and is uallay ontime. I recently came off the pill at the end of august, I did run 2 packets of the pill together June and July. we have been trying to concieve. I am currently taking pre-concieve pills and vitamin D. Due my period on Tuesday. on the saturday I found pink round spot with brown spot in the middle. On sunday and Monday when I wiped came brown with black bits in it, then during time of period, when I wiped it came pink lasted 3 days to a bright pink, disappeared now it has come back, all I get on the pad is brown discharge wipe its dark pink colour I am unsure if this is implantation or menstrual. Can you help?
