Was On Sulfamethoxazole For UTI While Pregnant. Had Unprotected Sex. Negative Pregnancy Test. Could I Be Pregnant?

Could I be pregnant? I have been on the pill now for 7 years (I have never missed taking a pill) and I had unprotected sex September 25th, and November 5th. We used the pull out method both times. But during September I was on a antibiotic for a UTI (sulfamethoxazole I think.) Now my last two periods have been SUPER light. This isn't regular. Usually my period comes like clock work for 3 days and then it's gone. This is the first time this has happned. The first period was for two days and was dark. The last one I just had was barely existent because I saw it once after going to the bathroom and that was it. I took a pregnancy test but it came up negative. Could I still be pregnant?

Hello!
The chance of being pregnant is very very low because :
you are on birth control
you used pull out method
periods
pregnancy test negative
Very light periods should be from the use of medication(birth control)
Take care of your self
