Antibiotics, period

I posted earlier this week but have a new update. Please read the whole post. Hoping someone else has been through something similar. Also please refrain from rude comments, this has been a learning experience and will be using a condom from now on.

I’m on the pill and take it every day at the same time, haven’t missed any. Two weeks ago on 11/29 I had sex without a condom and he pulled out before finishing. This was the only time I had sex, not after starting antibiotics.

On 12/3 I went to the doctor and was diagnosed with BV and given 7 days of Metranidazole to take. On 12/10 my STD test results came back positive for chlamydia (had gotten it back in October from an earlier thing, new partner has been told now and treated). So on 12/10 I took azithromycin. This week is also my placebo week and I usually start on Wednesday. It’s Thursday and this morning I woke up with cramping and brown blood and discharge that has been fairly light all day.

Is this from a combination of sickness, stress, and antibiotics or should I test?
