VERY thick after ovulation


Hello all! I have been looking all over and can’t seem to find any answers. So I figured I would turn to my trusty fertility forum! This round of clomid will be my 5th. I do not ovulate on my own and my endometrium has been getting VERY thick after ovulation (22mm @ 4DPO) I will be going out of town this month right in the middle of my cycle when I would normally ovulate. So my RE wants me to start my Clomid on CD8 and he upped it to 150mg. He wants me to super ovulate so we can do IUI when I get back. Has anyone heard of starting clomid this late and it working? Also, will my symptoms be worse this cycle with the increased dose? Any input would be welcomed! Thanks again ladies!
