Last month I started bc and I messed up my pills, so I bled all month on and off light or heavy. So my gyno said use a back up for of bc. Me and my bf used condoms sometimes, otherwise, we didnt. I just started my new pack of bc but, my boobs have been hurting, ive been tired a lil more than ushual and I get into spurts of where I want to eat alot then some days I barely want to eat. My back has been either just sore or hurting on and off to. Yesterday, a couple of times when I went to the bathroom I had a brownish black disharge but, it was dry not like when you bleed then it just stopped. Anyone no what it was and does anyone think im pregnant or is it just the pills? Thank you
