So confused!

BW
I'm on the pill, the lowest hormonal BC because my body can't handle any more than that. I've been on BC before for a long time and have been on it for over a year right now. 
I started dating my Bf in Jan, I'm pretty good about taking my pill before bed every day but I do occasionally miss it. Recently my Bf asked me if I was pregnant because I was being such a crazy bitch. I cried twice in 1 week and I am not a person who cries ever! 1 day/night last week I seriously peed 30 times but haven't had any issues since. I'm constipated with diarrhea coming and going.  Weird headaches every day...lower back pain. Slight cramping a couple of times...boobs have pains here and there. I took a test 2 days ago and it was negative. I went on with my life figuring it was something else but last night I dreamt I was eating chocolate 😂😂 I don't think that has ever happened to me! I'm about half way through my pack? Has this ever happened to anyone out of the blue?
