Hi there!! I'm trying to figure out when I'm due again, I usually have a 31 day cycle but last month I was 35 days, I had a bleed for roughly an hour on 17th November then nothing till 19th November which was normal. Would you class the 17th as the first day or the 19th? Did a test today which was negative,I feel sick on and off through out the day worse in a morning until I've eaten something which isn't normal for me. I don't know when the best day is to test.
