I've been taking sprintec for almost a year now. I take my pill at the same time everyday, I do not miss any pills. But everyday around 11am I start getting cramps and my stomach becomes extremely bloated and I start spotting. It's a dark red some times brownish color but enough where I have to wear a panty liner or tampon. It stops everyday about 30 minutes after I take my birth control at 8:05pm. Why is this happening? I've had on and off spotting with this brand some times but it's been continuous everyday for the past three weeks now.
