Chemical pregnancy 😔 need advice

Dani

So 5 days ago I got my BFP a day before AF, day of AF I also got a confirmed pregnancy 1-2 weeks on a digital test.. 2day I have started bleeding and clotting so guess I'm having a chemical pregnancy. I would have been 4weeks 5 days.

Question is do I class today my first day of bleeding as AF? I just dont know what to log to keep track of my ovulation?

Also how long should I wait before trying again? and has anyone experienced this and found it easier to catch following a chemical. I have read its easier following a chemical/missed miscarriage?
