2nd infertility-unknown

Hello. I'm in my thirties. We had one healthy child. We have just finished ten months of trying. I've cut caffeine, watched what I'm eating, non-smoker/drinker, and exercising. It was easy to get pregnant with my first child. I've been using glow during our entire attempt. Majority of the time the app was accurate on my cycles, last two months my cycles have been early and short. I saw a fertility physician, they are recommending explorative laparoscopy for possible endometriosis and hysteroscopy to remove a polyp. I'm nervous and wondering if anyone is frustrated or having a similar story.
