Oral progesterone side effects or pregnancy symptoms?

I will be 8DPO tomorrow. I have been taking 200mg oral prometrium (progesterone) every night since I ovulated.

Symptoms include:

-tightening of stomach/uterine muscles

-the weird feeling that something is in my uterus that is different

-mild cramping

-breast tenderness

-irritability

-bloating

-gassiness

Have you had the same symptoms and turbines out to be pregnant? I’ll test at 10DPO. So, pregnancy symptoms or the progesterone? Please spread all the baby dust on us ✨
