I am having a major issue I am having the exact opposite reaction. Lets start with normally my period is light and short (3 days). But throught the summer time the end of July I was told I had a UTI. So I took amoxicillin, I also pulled a muscle and had to take a pain reliever. Well since mid August I have had an 2 week heavy period every two weeks. Well I just thought that the medicines caused all of the build up that may have build up (since I was so light) come out. But now it is 4 months later and I am worried. I don't know what to do. Does anyone have any suggestions?? TY
