Hello,I am a 45 yr old female, no health issues except for HBP and am about 50 lbs overweight..light exerciser,.non smoker, non drinker and have recently switched meds to Valsartan due to cough from Benazepril. I have been on the new med for about 3 weeks and am now 7 days late on my menstrual cycle. I am sexually active but cannot be on BCPs due to my Mother s history of breast cancer....we do not use protection but showing no signs of pregnancy...have not taken a test yet. I am not perimenopausal either. Any idea??
