Hey ladies!!! I need y’all help!!!!!!!!!

I’m so confused and frustrated right now. I have PCOS and I was put in promethium and then clomid 3-7. Today I’m 15dpo and 14dpiui (no trigger shot ) I tested today and negative and no sign of my period either! 🤦🏼‍♀️ i don’t know if I’m pregnant and is too early for hpt or probably my levels are low. Should I call the dr office to request a blood work ? Or probably af will be late this month too. But if I ovulated 15 days ago I’m supposed to get my period for sure in these days right ? I’m so sorry for too many questions but I’m so confused !!!!!! Thanks in advance
