I have had my implant for 1 year and 7 months, when I first had it put in I spotted for a couple of months on and off and then since then I have had no period what so ever, we have been so busy recently that we haven't sex in about two weeks other than earlier today. A few hours after I noticed that I was bleeding, I never normally bleed after sex and it has worried me, as my partner and I are not ready for a baby yet hence why I have the implant. Could I possibly be pregnant?
