Pregnant or pms

Okay so i came off the pill 2 months ago and i have had my first period this ones a day late but i know it will be out of wack for the first few months. I have had headaches for the past 3 days, i have a cold, cramps, nausea, dizziness, hungry all the time and have aversions and cravings, I'm really tired all the time no matter how much sleep i get, sore sensitive swollen nipples and I'm moody. I took a test yesterday and was negative and because my cycle is all out of wack i dont when to take one again. Please put your opinions across. 😊😊
