could i be pregnant?

Rebecca

Hi guys, so I am currently on birth control. I had an ear infection so they prescribed me some amoxicillin to take for it. I know antibiotics do not cancel out birth control, but im afraid im pregnant. My nipples have been hurting for 2 days, but only to the touch. My boobs are not sore or swollen otherwise. Other than that i have been feeling very tired lately. I am expecting my period in 8 days. I took a pregnancy test today to see but it came back negative. i think it might be too soon to take one though. Someone please let me know what they think. Im not sure what else may be causing the sore nipples, being that this has never happened to me before. we also always have unprotected sex.
