Femara vs clomid?

Veronica • Pcos. Pregnant with baby #2. Had baby #1 2016. Had help with both💉
I get to make this decision next month .. The 100mg clomid didn't work for me this month so I can either higher the dosage or switch to femara.. Also y does it look like femaras side effects r worst then clomids? Which have u had success with?
