Pregnant or not Pregnant..?

Kyra
So my last period was January 16-22 and it was t really normal it was more of super painful cramps to were I was throwing up, first two days were spotting, 3rd day was heavy, 4th and 5th was light/spotting and the last two days were brown spotting. No cramps after first two days. My breastf were very sore and sensitive two weeks before my period and grew in size by a cup almost, they are still very sore and sensitive today, I pee a few more times a day than usual, I eat small amounts and feel full then maybe 30mins to and hour later I'm hungry again and I always feel like I'm about to throw up around 2am and last for a few hours. Back pains, headaches, emotional, moody, and craving sonic drinks the vanilla cream Coke. Idk if I'm pregnant or not..?
