Pcos struggle

Anybody that has pcos and had an IUI and it worked? I feel like if im out, this is my first one and did a test on day 11 piui it came out negative, no symptoms other than sore an sensitive nipples and breast and very sleepy, I had cramping on my left pelvic side on day 9 piui and it went away... Im on day 12 piui, also im taking endometrin via vaginal and I kinda wanna stop taking it cause I feel like if im out and keep taking it I wont get my period... when should I test again? Any recomendations?
