If you have had a chemical pregnancy, when did AF arrive after? 4th, 5th, 6th November had faint lines on tests, started bleeding on the Friday so the 8th, bled for 2 days. When can I expect AF, can it take longer? I never bothered going to GP or anything as the blood was fresh and I was sore, I have been cramping again this week for a couple days again but no bleeding.
