Is white, very abundant and sticky mucus normal on the 9th day of the cycle when using Vibin Mini?

I'm on the 9th day of the cycle. My calendar shows that in 7 days there should be ovulation, but I think this is broken because in June I had two periods through an irregular cycle, and in July one day of bleeding. I take Vibin Mini tablets to adjust menstruation, but it is still irregular. From 2 days I have slime white, very abundant and sticky. I will point out that from 7 days I take the antibiotic Xifaxan. Is such mucus correct on this day of the cycle? If not, can antibiotic therapy be induced? Please reply
