TTC baby #2 after 4 years! (PCOS)

I’m 34 years old and my first baby boy will be 4 in July. We tried for over two years to get pregnant with him and then ultimately did IUI after being diagnosed with PCOS and a slight tilt to my uterus. It took the first time and I had zero problems with that pregnancy or delivery. We decided recently that we wanted to go ahead and complete our little family and go for one more. I got my Mirena IUD removed this past Tuesday (5/21) and my Dr. put me on 1000mg of metformin. We wanted to try on our own until we got back from vaca at the end of July and then if we weren’t successful start the IUI process again. Anyone with similar experiences? How long did it take you to get the BFP the second time around?
