Naomi,

Firstly, congrats on the pregnancy... and hope it sticks. Sorry to hear about the bleeding.

I have PCOS as well and have been on Metformin for 6 months as well (although am still not pregnant).

If you have PCOS /IR and conceived on Metformin, generally docs consider the benefits of staying on it during the pregnancy to outweigh the risks. I think most women stop at 14 weeks, but some, if their blood glucose levels are rising during the pregnancy, will stay on it for the whole pregnancy.

I don't know anything about the relationship between Metformin, PCOS and migraines. But what your docs says about Metformin doesn't sound 100% right... it is an insulin-sensitising drug and insulin is a hormone. My understanding is that the endocrine system is a perfectly assembled orchestra and if one hormone plays out of tune the others try to compensate for it. So I would say that Metformin has more of an effect on hormones that we tend to think, simply because it is helping to control your insulin.

**RANT**I have a big dislike of the whole "metformin just makes you lose weight" line! I am a "normal" weight woman with insulin resistance... my weight doesn't come into the equation, but my insulin still does. Yes, for some women, the weightloss will result in ovulation being restored without the need for Metformin, but for other women, this is not an option, since they have no weight to lose and yet their insulin is still too high.**END RANT**

That doesn't help you in your situation though. Are you on a high enough amount of folate? Are you taking any aspirin to help with the clot? (Don't take the aspirin without first talking to your doctor). Folate can sometimes help with reducing clotting, since homocysteine increases clotting and folate can reduce homocysteine levels (and homocysteine is often elevated in women with PCOS). The Elevit tablets contain a good amount.

Maybe talk to your doctor about taking aspirin, if you are not already taking it. I'm not a doc, but I know some women w/ PCOS take half a tab throughout ttc and pregnancy since it can help some women w/ PCOS to reduce their chances of m/c'ing.

I'm not an expert... but hope this helps in some way.
