I Am Post Menapausal And I Have Been Spotting For

I am post menapausal and I have been spotting for 1 month. I have period type cramping and lower back pain. I am also experiencing bloating. My cramping increases with a big meal. I have also had 3 bladder infections in a year. I have never before had bladder infections. I decided it was just because my pH changed with the menopause.
