My tubes are tide for about 4 years now. I have been on birth control up till 3 months ago due to irregular periods, I just had a pap smear that came back clear, and started the day after. I bleed heavily for about 4 days and have been prescribed medroxyprogesterone to control the bleeding. I have also just started taking a blood pressure medicine and am on my second week. I am 36 and have a sonogram scheduled on monday to prepare for an upcoming hysterectomy within the year. The problem is i started spotting and cramping last night and today actually had to use a tampon. It is a very drk brown and thick color no abnormal odor. But strong cramping, i get a headach and nausea right before i start and it brought me home from work. Should i be concerned and contact my dr a out this or just wait until monday for my sonogram. I feel better this evening but have been abnormally tired and my blood test came back not anemic. Just need advice. I am still cramping. Sorry this is so long.
