can someone please help me💖

I'm turning 17 and I've been with my boyfriend for two years, I've always taken the pill for birth control but stopped it two months ago for personal reasons. I'm due on my period tomorrow but I don't feel like I'm due on.. my body isn't the way it usually is before my period. I've been getting this really sharp cramp pain in my right side of lower tummy but it stopped a few days ago, I've been feeling sick and had really bad aches in my legs, had headaches and just feeling abit odd, has anyone else experienced this as early signs of pregnancy?x
