Need some encouragement!

Just starting third cycle of timed intercourse with meds+hcg shot. Had a chemical pregnancy the first cycle, nothing the second cycle. Tried for a year with irregular cycles before being diagnosed with PCOS. Have regular cycles now. Have decided to try until October this way and then start talking IVF since our doctor told us IUI wouldn’t improve our chances much if at all over timed intercourse and even that is prohibitively expensive. The price of IVF makes me feel sick though...
