Late period

Dana • 🐎🐖🐂🐕🐈

I stopped taking my BC pill last month after my period. My husband and I have been TTC since then. AF was due on Wednesday.. still no period or signs of period coming. Took a test yesterday, it was negative. Is it possible that I’m pregnant even though it’s showing negative, or my BC now is causing my period to be irregular. Any one in a similar boat?
