Hi ladies!
I had an IUI today, my 4th one over the span of almost 3 years, with some IVF's and breaks in between. I had my u/s yesterday, had 3 mature follicles, so my RE said to trigger and do IUI on Sunday. I said I am an extremely early ovulater (when cycling naturally, using OPKS. I can get a smiley face, then a few hours later get a stark negative

) so he said ok, then you can do your IUI on Saturday. So, did it today with a different RE who was working this weekend. He did my u/s and only found 2 follicles and a small one that he said I already ovulated. Even though I ovulate early, I have never already ovulated on CD 12, prior to a procedure. Has this happened to anyone else? He went ahead with the procedure since I still had 2 mature follies. I am kinda bummed bc I have had 4 before (most all other times) and gotten a BFN. Just grasping at straws as usual

Also, my new RE also does something called an HCG booster 5-8 days after IUI to give an extra 'boost', but I kinda feel like this round is a bust because of all the circumstances, so not sure I should even waste my time and $ on this extra shot. Any thoughts or advice?
TIA!
