Last November I was on an antibiotic for a UTI and that month I had brown spotting a week before my period. i thought that was odd but blamed it on the antibiotic. My period never went back to normal. For the past year I have had 4-7 days (sometimes as much as two weeks) of brown spotting before my actual period. (My period has remained normal every 28 days). Could that antibiotic messed up my hormones or is this just a coincidence? I finally went to the doctor last month. She said it sounded very hormonal (as the brown spotting usually follows sore breast and other slight pms symptoms and it has been following a pattern). She put me on birth control. I was so excited thinking I would finally put and end to this however I started spotting 8 days before my period was due on birth control. She said it can take up to 3 months to regulate. Do you think birth control will fix this? I almost felt like the pill was a placebo as it did absolutely nothing to effect the spotting. i shold mention my pap and physical exam came back normal. I have felt very hormonal in terms of mood and sore breast when the brown spotting occurs. Any advice or ideas as to what's causing it would be great. I am so frustrated. My period has been consuming 2-3 weeks of my month for the past year!
