Will I ever conceive again?

I am 31. I’ve been diagnosed with PCOS. I don’t have any cysts. I ovulate fine for most part but my cycles are irregular. I’ve been trying to conceive for 2 years now. I ovulated on this cycle and BD when I was supposed to and yet today I’m spotting which rules out pregnancy this month.

I already have 1 child. I’ve been prescribed with Metformin, has anyone had any successful pregnancy taking this? Any advice or recommendations would help. Thanks in advance!
