New and nervous

Sydney

So hey everyone!! I’m new my boyfriend and I have been trying for 4 months to get pregnant. Went to the doctor got put on some medicine to induce a period. Supposed to be ovulating this week. Little more back story I have PCOS and was on BC for years. I had an IUD and had that removed never had a period until said medicine. My question for all you who have been through this is how many cycles do I need to go through before I start knowing when I will ovulate and so forth?! I’m trying to be happy because everything is going great but I’m terrified I will not ovulate any advice??
