Follicles started growing after ovulation. How does this happpen???

A little background on me.  Start infertility treatments about 1.5 years ago.  Was told I am a poor responder to meds.  This last IVF cycle, my antral follicle count ws 11 (6 on right 5 on left) RE had me take the highest doses possible and only had 4 follies on right and 1 follie on left start developing on the 1st u/s.  3rd u/s showed 2 follies taking off on right, 2 lagging behind and the 1 on the left died off.  I decided to change to an IUI since i only had 2 big follies.  Well after HCG shot and IUI, I started having bad pains on right side the day after the IUI.  6 days later the pain was still there, so RE had me come in for u/s.  Right side showed a nice size corpus leteum and some fluid, indicating I actually ovulated. Very exciting!!  But when he looked at the left ovary, I had 4 developing follies!!! WTH!  He didn't measure them, but they looked to be about 12-14mm.  How does this happen. During stims only 1 grew and never got over 10mm.  How did these 4 stat getting bigger??  Has anyone else had this happen to them.  RE seemed surprised by this too.  Please help!!

Hi,
Could be that you have cysts remaining after ovulation. Or, as my RE said during my 1st (failed) IVF, the follies come in waves which is why we had 8 growing and 4 more that appeared midway through stim. This could also be what you saw. Keep trying, you should succeed because you are still plenty young. You only need 1 good egg! Good luck!
