Random Cravings and Symptoms

Hey ladies! I'm pretty wierd. I'm super picky with my food and never really enjoyed things like Cinnabons and Icecream. I know I know. I must be crazy right? I have been TTC and although I just went through a bad break up I'm thinking I could be pregnancy right now even though the test was negative. I'm thinking it's too soon for it too be accurate yet. Anyway...I'm eating tubs of  Butter Peacan Icecream and having a lot of other pregnancy symptoms. Sore nipples, acne, irritability, back pain, and cramps. I could be PMS but I feel off. It's so random. Has this happened to anybody else?
