New to IVF, Introduction

Hello all, I'm 39 now and have been trying to conceive for the last 2 years. January 2019 we did IUI but it failed... I have a blocked left Fallopian tube, fibroids and thin uterine lining to add to the mix. We've decided to go the IVF route due to all my issues. March 27, 2019 I started my stims... a host of medications including Lupron, Follistim and Menopur. I went to the doctor on day 5 Monday April 1, 2019 and he says I have 6 follicles <10 and 1 at 11 so I don't think he was very happy with the size of the follicles. I go back to see him on Friday April 5 and this will be day 10 of stims. I'm hoping I will have more growth and more follicles. Has this happened with anyone else? Is slow growth normal? I take the highest amount of medication he can prescribe. I'll admit I'm feeling bummed about the last doctor's visit. If all goes well we will have egg retrieval sometime starting the week of April 8, 2019. Fingers and toes crossed!
