Chemical pregnancy again

[Verydonut]

I have two DD. We have been trying for a third for over a year. I've have two chemical pregnancies, the most recent being last week.

I have PCOS and had no trouble conceiving my first two, but it just doesn't seem to be happening now. My cycle follows no pattern, and it can be 4 weeks between periods or it can be upwards of two months. Is there anything I can do or take in order to regulate my cycle?
I'm trying not to stress about the situation as I know that will have an effect on everything but I can't help but worry and I really don't want to experience another miscarriage.

Hiya, I have pcos, my cycles are irregular and I had strange patterns of CM, amongst other symptoms. I started taking inofolic last month and I noticed a decrease in symptoms after that month. This month I took inofolic and tried preseed lube and I've got a bfp for the first time! I cant say for sure if it is linked but looking at the research into inofolic and pcos it certainly helps! Good luck xx
