I am 28 married with two children. I have never had this happen. I am on BCP and have been for 13 years. My periods are NEVER late, anyway my last period was 12-25-08 and so my ovulation time was Jan 5-10 I think and me and my hubby had sex around this time, I missed 1 pill in the 2nd week of the pack but took it the next day with that pill around this same time I was on antibiotics. My period was due 1-22-09 on 1-24 I started very light pink spotting with some clear slimey mucus but only when I wipe. I out a pad on but nothing only a little when I wipe and not every time I wipe. I have taken 2 Preg. tests and they are negative, today 1-25 still nothing really but a red streak of blood only once when wiping?? I am very confused as to what is going on, could my body be messed up from taking 2 pills at one time and the antibiotics or could this be Implantation and I be pregnant?? Please HELP!!
