Ovulating within 24 hours of getting the HCG shot.

Every time that I have been triggered, with the exception of once, I have ovulated within 24 hours of getting it. This concerns me a little since the doctors say it happens between 36-48 hours. If we do have IVF and they trigger me too soon, we would be out of a lot of money for the drugs. Since I have a low egg count, more money will be spent on meds than the average person, this could really suck. I have talked to different doctors at the clinic about this before and they told me not to worry about it, but I can't help to be worried. Yesterday I had the HCG around 830am and today my temperature sky rocketed. My EWCM has totally disappeared and the very painful ovulation pains that I have been having for the past few days are also gone. Yesterday we went out for dinner and the only thing I could think of was how badly my ovaries were hurting. I had 2 follicles on the left that were 21, 23mm. I had one on the right that was 15mm. I'm guessing that all 3 of them ovulated because shortly after the trigger shot my right side started to hurt more and more. The last time I had 3 follicles was on Gonal-F. I believe the Gonal-F was around $1300 and Femara is like $6 with insurance, Gonal-F isn't covered by insurance :(. i think it's funny how 2 differently priced drugs did the exact same thing to me. It's too bad that I never know what will happen with Femara. Most of the time it gives me one follicle, but once in awhile it gives me more. DH's work has changed insurance, so I'm very curious to see if any fertility medications are covered. Where I live there is no insurance company that covers infertility procedures like IVF and IUI's, but I know that some of them will cover medications. If we could get fertility medications covered, IVF would be half the price. Clomid isn't covered by insurance because it's only used for fertility, but Femara is covered because it can also be used for breast cancer. I'm hoping to find out within the next couple of weeks to know if the new insurance will cover anything fertility related.

PS,
I'm very sorry for any grammar mistakes I have made. I am horrible at writing.
