I have pregnancy symptoms, but test negative

I generally have a 26 day cycle, I was due to start my period on the 12th. I generally wake up in the AM with AF, with heavy cramping the day before. I do get a little emotional the week before, and crave chocolate during. Last week, I noticed my mood swings I knew AF was coming so shrugged it off. I have been a constant ball of up and down emotions, irritable, lets just say I'm driving myself crazy. I've had some cramping off and on, and now mostly off. The evening that I should have started I had some brownish type mucus, not alot just some on the TP, then a tiny more the next day. I've noticed I've been way more tired lately. Im STARVED, and I'm not craving chocolate, I'm having cravings for food, lasagna(I never eat that), carbs, the good stuff, lol! The past few days I have been feeling nauseous at times, twice at night at around the same time, and once during a shopping trip. Im BLOATED, like no other, I even look pregnant, my belly has just decided to pop on out, I guess its all the carbs. Im burpy alot, gassy as well. My boobs do feel more heavy, but they dont look bigger and my nipples aren't darker.

I'm in a relationship with a guy for about 7 months now, this isn't what either of us are wanting we are both single parents. However, I'm always willing to share more love. I haven't been under any stress lately, everything is going pretty smoothly in my life. Im on BC, but conceived my last child on that as well, so not sure how much well it works for me. I feel like im having the early symptoms of pregnancy, and honestly feel pregnant. I took a test, cheap dollar store brand yesturday afternoon. It was negative, I have another to take in a few days if I still havent started. I know i've rambled alot, but I can't share this with anyone I know right now, what do you ladies think?
