Help me!

So I didn’t have a period all of February. March 3rd I began to have my period, at least I think! I had a normal period flow the 3rd and 4th, then it stopped, then I began spotting pink the 6th&7th! Now I’m currently nauseous every morning, I’ve started to sweat way more than normal, I’ve had small cramps in my left pelvic area and towards the middle. What do you guys think?!
