Follicle count low

Hi group. Hope everyone is well!! So far I’m on day 8 of menopur and gonal F, and I only have 4 measurable follicles.....only two of them are at 12mm, and the other two are a slower growing. Has anyone had successful IVF with such a low count? I’m freaking out that they will cancel my retrieval. They said my estrogen levels are going up which is a good thing. I’m 37 and have a low count to begin with...just looking for some happy outcomes, advice, or encouragement! Thank you!

Sincerely,

Super scared 37 year old with low follicle count and a burning desire to be a mommy!
