Periods Are Different When Your Trying

My husband and I have been trying for over a year, had two miscarriages and now it's been about 4 months since we started trying again and now everytime I get my period I get very upset and cry. Sometimes it feels like God is punishing me for waiting until my 30's to get pregnant but I wanted to have a career first. Now I've changed careers side hustle and 9-5 which is suitable for having a child and yet we haven't got pregnant again. We have been getting a tonne of tests to look into IVF but I still don't know how to not get upset whenever I get my period. I want to be a mum so bad.
