Weak during period

Melanie • 18

Yesterday I got my period and today just an hour ago, I started getting extremely bad pressure pain in my lower stomach and felt extremely weak. I still feel weak and the pressure is still there

I've NEVER felt weak during my pd so this isnt normal for me.

Im 18 and have had my pd since 13. The last time I had sex was a month ago but it was protected.

Is there something wrong with me?
