Being referred to fertility

I was just wondering if anyone can give me any insight into what's to come. I'm 32,my OH is 31. He has a child from a previous relationship, I have none. I think I have mild endo,but not entirely sure,we just know it's not happening without some help after over 2 years ttc.

Im just so confused as to what will happen now/next. I've tried to do some research but in the UK it seems to differ from area to area. I've been referred to fertility this week,my OH is going for his sperm count and I'm having bloods done again cd 15 so they are ready for when we have our first app.

Im just so clueless atm and could really do with knowing a bit more what's going to happen 🤞
