Ovulation and Femara

I am 10 dpo today. I ovulated on 5 mg of Femara and still waiting for the results of my day 21 progesterone. Negative pregnancy tests and I’m pretty positive I’m not pregnant. Do you think my OB will prescribe me 7.5 mg since I didn’t get pregnant or will keep me at 5 mg since I did ovulate? Also has anyone had luck on pregmate tone suppositories? Thanks!
