Concerned?

I had a few faint positives before getting my period. Very very light positive, might’ve even been an evaporation line. I got my period like three days ago and have been having serious cramps. My period is usually very light and easy. And I’ve been getting more than usual bigger blood clots coming out. I just had one that was pretty big, I took a picture of it. Will post if people wanna see... but should I be concerned??! My cramps are making me wanna pass out and usually by day 3 of my period it’s already almost over ?
