So i missed my period march 20th. Accidently missed a few bc pills the past month but took them as soon as i remembered. My fiance and i have sex regularly and depend only on my pills. The last 4 days and today, so 5 days total ive had brown spotting. No pink or red. Not much either, one liner can last all day. My next period is due april 17th. So one week away. Ive read that this is about the time implantation usually happens but that it only lasts for 1 to 2 days. Ive been spotting for 5.. Also breasts are a little tender, not much. Increased appetite. And sleeping more. Any help appreciated. Pregnant or not?
