I am on sprintec 28 and I am on the Friday of my third week so right before my period week. My symptoms seem to change each month so not sure what to look for each month. With being sexually active I know I am 99% protected from pregnancy but that other 1% scares me. I am having so cramps, breast tenderness, stomach upset and some brownish/white discharge. Is this my period coming or very early pregnancy symptoms?
