How soon..

So I had an IUI last Wednesday. The sunday before according to glow was 29% chance and we had sex. Since the day of my IUI I have been cramping more then anything and sick (throwing up). This week I am still have stomach pain, like feel like my stomach is so tight. I was given progesterone which I am having an allergic reaction too 😩 (I already talked to the doc and stopped using them).. Technically I am still a week away from testing but with my daughter I knew a week before missed period (pregnancy test). You think it would be way too soon to test? Thank you for any insite this is the first IUI that the cramping has been so bad I can barely move and got this sick.
