My husband and I always have unprotected sex. recently I had switch birth controls from the implanon (didn’t catch my periods on the birth control) because I was severely cramping as if I had my menstrual cycle but they didn’t do a pregnancy teat at the doctors office. I switched to the sprintec which I started immediately and didn’t touch my husband until 7 days later..now I’m on the placebo side of my pill pack and I am waiting for my period to come down......should I be worried ??
