Letrozole symptoms?

Shauna • 🌸TTC #1•PCOS•🌸

So I took my five days the 3rd-7th. Got a positive opk 10th at 1:30 am and tested again this morning(12th) at 1:30 about and still had a positive. Been really nauseous and crampy and bloated. Also had a bit of a temp rise today of about 2 degrees. Is this regular for you other ladies taking it? And if so what else should I expect. And for those who had success with letrozole what were your first pg symptoms?
