TTC Clomid?

hi girls

Am new heard and I’d love to talk to someone who is in the same situation as me.. been ttc tfir about 3/4 years. was diagnosed with PCOS about 8 years ago. Had some cysts removed with surgery but they grew back again. I suffer from awful period sometimes cycles lasting 55 days. I went recently for a hsg test and it was awful painful to find out I have one tube blocked. Went back to see my fertility doctor today, he isn’t concerned about the tube. He started me on clomid? Anyone had any success stories on this and is it true about the mood swings it can give you? Thanks M x
