Welcome to the EmpowHER community. I will try my best to help you, but you may want to talk about this with your gynecologist.
Oral antibiotic, including sulfamethoxazole/trimethoprim (Bactrim®) have been shown to interact with birth control pills and potentially decrease the effectiveness of estrogen-containing oral contraceptives
Spotting - or 'mid-cycle' bleeding - may be the first sign that an antibiotic is interfering with your birth control pills and lowering their effectiveness.
To help women avoid pregnancy while taking an antibiotic - and for at least one week afterward - doctors generally recommend they use a condom or spermicide as a back-up method of birth control in addition to remaining on birth control pills.
I am concerned that the light bleeding which lasted only a day and a half might have been implantation bleeding.That is why I suggested talking with your gynecologist who may say not it was not or may order a blood pregnancy test to confirm the negative results of the hpt.
