I NEED ADVICE!!

I have PCOS, I have been trying to have a rainbow baby, but I can't seem to get pregnant. I just had AF last week and 3 days later I was heavy bleeding with some egg white mucus and brown blood (tmi I know). Well tonight I have been very fatigue, having to pee every half hour, bloated, hungry and moody. I've also been bleeding very lightly. I used to be on metformin but can't be on it because it makes me sick, so what would help me be able to have the little baby I've been wanting? Someone help me please?
