Clomid 150mg

I’m on my fourth round of clomid and first round of 150mg. I feel pregnant on 50mg and on 100mg (once we added preseed) but miscarried both times. We decided to take two months off, and yesterday was my first time taking 150mg.

Any advice on how to make sure this baby sticks?? Any vitamins or herbs I can take to assist? I just am hoping for the best but I’m very anxious because I know how this ended last time. Any advice would be helpful, thank you ❤️
