I’m hurting so bad

So last month was the first month we ttc and I just started my period today but I’m having the worst cramps I’ve ever had and idk why, I’ve always had cramps during my period but not this bad what do y’all think it is... I don’t think it’s pcos or nothing like that bc this is the first time ever doing it this bad and it’s just weird bc last month was the first time we ever tried to get pregnant...

My period isn’t heavy at all it’s just a little blood
