symptoms!

I dont know how to figure this out lol. Yes I do have a test but AF isnt due for another 3 days (21st) - I also came off birth control in May so who knows when my next period will come but I did have one in May and June. Ive been pretty moody, and emotional. Ive been tired constantly. Like no matter how early or late I go to bed I just want to keep sleeping when I wake up. Ive had some minor back pain, I have thrown up a bit but it hasnt exactly been In the morning, more when I come home from work. And the cramping! Is cramping a symptom because I havent stopped getting cramps throughout the day for like 5 days now, ive been saying to my boyfriend that my period should come any day now but I have nothing. Also a sudden craving for baked beans and eggs, like every day for the past 3 days. Please tell me your symptoms! I'm on cycle day 30. Last cycle was 25 days but again- ive recently come off birth control. Advice? Can you tell me your Symptoms? Thanks heaps! ♡
