Hello, I have been bleeding for 6 days and I am not expecting my period till next week. My last period was 9/11 and I have been regular for the past 3 months, 28 days exactly. Previously I was on depo and I just started having my periods again 8 months ago and have been regular for 4 months. I did have intercoarse on 9/22 which following my calendar would mean ovulation and exactly one week later 11/29 I started bleeding. I thought implantation bleeding however it's been 6 days. Why would my period come two weeks early? This is so frustrating...
