Don’t know what to think!

So I’m currently on my 5th cycle of clomid. I did one at 50mg and nothing happened. Then we did one at 100mg and I ovulated but didn’t conceive. Third round we did another at 100mg and nothing. So fourth round we upped it to 150mg and again I ovulated and still didn’t conceive. The last two periods I’ve had have been very light and only lasted 3 days. My period used to be heavy the first day or two and then normal flow and lasted 5-7 days. The medical side of me is beginning to wonder about my uterine lining. So I look it up and come to find out excessive use of clomid can cause the body to underproduce estrogen which then causes the uterine lining to be too thin. If it’s too thin then the fertilized egg won’t be able to attach!! I think I’m going to be calling my gyn in the morning!! Both times I ovulated I know we bd more then enough and his sperm analysis was excellent so I know it’s not him. I just don’t know what to think now.
