Ive had 3 miscarriages now and been told ive got factor 5 leiden heterozygous blood clotting mutation. Ive not had a lot of help so far except been told to start taking aspirin and heparin injections from 6 weeks pregnancy however i cannot even make it to 6 weeks! Ive done my own research and seen a lot of people who've had multiple mc have taken low dose aspirin from 1dpo or BFP. Just wanted to hear from anyone who did this and was successful and what dosage 75 or 150? Or any other advise?
