Progesterone side effects?

Katherine
Anyone else have experience taking progesterone post <a href="https://glowing.com/glow-fertility-program">IUI</a>? I feel like it's a cruel trick that the effects are the exact same as the symptoms of early pregnancy!!! That is BANANAS. So do I go through the tww with nooooo clue as to whether or not I should be either optimistic or prepped for bummer news when it comes time to test??
