I am 25 years old and have been on BC for 3 months, June 3rd I had my gallbladder removed, I missed 2 pills because of the surgery and was on antibiotics. I have been sexually active with my Fiancé and I am now 3 weeks late. A month ago I had brown spotting for a day (barely anything) and For the past 2 weeks I have been extremely foggy with my thought process, nauseas for no reason, my breasts are really sore and I am very emotional. I am currently looking for a new OB and in the mean time I don't know what I should do. Could I be pregnant or Could it be from the surgery or missing the 2 pills? Last week I took a HPT and it was negative.
