The last two periods I ve had, the blood has been rather chunky. Never before has it been that way. My last one was Oct. 5-10 and just started again on Nov. 29, it s never had that large of a gap between them either. I ve been using the birth control minastrin since August. Also in early October I had a UTI, yeast infection, and was told I had chlamydia, which I thought was all taken care of... Why am I still having this issue????
