What’s your insight?

I recently stopped taking pills last march 7 as i can remember. Taking pills was an advice from my doctor since i have PCOS. But i cant handle the hormones changing. I have regular cycles or period from 21-27 days. My last period was march 28. I am now 33 days delayed. Could i be pregnant or its just delayed due to the pills? I take PT btw but it was negative. My nurse says its too early for now to detect it. I should be waiting for a week. I am so confused right now.
