Had a period starting 9th November and was TTC. Then on 4th December temp drops and got my period so assumed that was that (had period pains which is unusual). A couple of weeks later, using OPKs and got positives 8 days in a row so realised I was 6 weeks pregnant. It did explain a few things, eg heartburn and migraines. A few days later I had a miscarriage. Anyway, I just can’t make sense of that period that wasn’t really one. It seemed far too heavy for implantation bleeding. It was 3 days of spotting then 6 days of normal bleeding. Is there something wrong with me? Blood tests revealed poor thyroid function and low folate. Also has anyone had this and found the cause and then gone on to have a successful pregnancy?
