Did anyone else get breakthrough bleeding on Metformin that they contribute to the Metformin? I had a MMC the beginning of June. I started Metformin a few weeks later. About 2 months later AF returned. I had bleeding THROUGH ovulation and then had spotting about 9DPO. I did get positive pregnancy tests (though VERY, VERY light) at 7DPO (though it could have been hcg left over from MMC). I had pink/ brown/ red blood clot spotting at 9DPO and the tests got lighter. I honestly feel I had a VERY early chemical, but have no way to know for sure. I'm now on my second cycle (I got bleeding when AF was due, but it may have been bleeding from a chemical instead) and had ovulation symptoms VERY early (looks like maybe CD7) and I'm now getting pink spotting a week after. I'm wondering if the Metformin could be causing it (but hoping it means I may be having implant again, but doubtful because my temps are doing crazy things). (I'll attach my chart, if anyone can make any sense out of it.)

If anyone has any idea what's going on I'd love some ideas too.

Thanks!
