So I had the implanon for 11 months. I was very regular with AF until the BC which is why I got it taken out in June due to irregularities. My partner and I had unprotected sex during my fertility days in Aug. I took 2 first response in Sept. (6 days sooner) than my missed period. I took then an hour a part and both came out positive. However, yesterday I started to have what looks to be a period with cramps. I had a blood test done today and it came out negative. If I would have been pregnant I would have been 3 weeks. Around this time last year I had a miscarriage (2-3) but the blood test never detected my hormones. I was told I am a high risk due to an abnormal uterus. Any help from anyone would be greatly appreciated!!
