Fertility drugs otc

I’ve been on clomid for two months and haven’t had any positives. I would typically think it’s a drug that doesn’t work for me but I’ve got pregnant off it twice (one I had a baby, one miscarried). Since it usually works for me I wanted to give me body a break and give it one shot.

Two questions has anyone had a pregnancy and had the mg matter. I was able to get pregnant twice at 100 mgs but 150 mgs nothing happened?

Secondly, in the meantime before I go back on the drug is there any supplements I can take to boost my hormones/eggs.
