Femara and period question

Samantha • Mommy of 2! TTC #3. Ectopic 3/29/18 Waiting on my 🌈👶🏼❤️

So I am on cd 31 right now, I took femara cd 3-7 and pretty sure I ovulated but I got a negative pregnancy test this morning and no period yet. Doctor wants to start provera again and do another round. Do most women get their period after taking femara, or need help if they didn’t have normal cycles before?
