5 days late

Kayla

So I had a UTI back in July and I had stopped taking my antibiotics on the 26th of july. My period was supposed to be here the 1st of August and I still don’t have it with no signs of it coming. I’ve taken some pregnancy tests and they came back negative. Could the antibiotics not allow me to have a period? Can I still ovulate? I’m trying to have another baby 😕
