What do you ladies think?

So a little over a year ago my husband had a seman analysis and they recommended

IUI

bc he has slower swimmers.we had already been trying before that test. Well we kept trying on our own and months after that test we conceived naturally and it was ectopic. 4months later pregnant again but mc very early ppl call chemical pregnancies. Well we have continued to try naturally until this past month we went ahead with

IUI and I found out today it didnt work😕 I know the first time usually doesnt and we are going to try

IUI again with trigger shot again. So do yall think we have a good chance at this working since they did recommend it because his SA but we also conceived naturally? I'm feeling a little down and it crossed my mind like is this good for us or should I look into

IVF. I have a friend who says since I've gotten pregnant twice naturally then this should definitely work for us. Thank u ladies! I have 3 kids with my ex husband never had any issues before.
