My Dominant Follicle Grew 5mm in One Day. IUI tomorrow

So, I went to the doctors today to have the usual ultrasound and blood test. I think the doctor said that I have 4 follicles? He said that 3 of them are too small, but my dominant follicle is 24 and ready to go. Yesterday it was 19 and the next day it's 24? That doesn't make much sense to me. I don't understand why medication makes one of my follicles grow super fast, but the other ones hardly grow at all. I thought that the medication was supposed to give you more follicles, not make one of them go out of control and grow rapidly. I'm only on cycle day 8, isn't this too early to be having a follicle that big?  It's funny that I ovulate too early on mediation but ovulate late without any medication. I don't know what is going on with my body, but I don't think it's doing what it should be doing.

My doctor told me to trigger today and have the IUI tomorrow. I'm pretty sure that my LH started to surge before my HCG shot because this morning my ovulation test looked positive. I wanted to wait one more day to trigger because I was pretty sure that my blood test this morning would have shown an LH surge, but the doctor told me not to wait just in case. On CD 3 I told the nurse that I wanted to do a back to back IUI, but when we went up to pay, the receptionist told me that they don't do that anymore and that if I wanted it I would have to get permission from the doctor. I thought that since I told the nurse what I wanted to do and that she was fine with it that it wouldn't be a problem, but I guess I was wrong. I'm going to ask the doctor who is doing the IUI tomorrow if I can come back the next day for another one, but I have a feeling that they will say no. Maybe there's no point in doing a second one anyway, it could be too late. I don't know why I want to have 2 IUIs since I'm 99.99999% sure it won't work. I would say 100%, but nothing is 100%

DH quit smoking in the summer and started taking vitamins a few months ago. I'm pretty sure that I'm the problem and that my eggs are just too shitty for a successful pregnancy, but I'm curious to see if quitting smoking and vitamins has helped my DH's sperm count. It's always less than 10 million after a wash. We will see.

We have to go in between 7-8am to drop off the sample and then go back at 10am for the IUI. Then I go back for an ultrasound and blood test the next day to see if I have ovulated.
