Period or Early pregnancy symptoms

Samantha

On cycle day 21 first round of clomid my progesterone levels were a 7.9. Is it possible I could have ovulated later and what I’m experiencing is early pregnancy symptoms?

Symptoms:

Heartburn

Cravings

Fatigue

Bloating

I realize period and pregnancy symptoms are very close to each other. Period is due in 3 days. Any input is good. Thanks
