Sharp pain


So I’ve been having some cramping the last few days. And I started very lightly spotting this morning. ( only when I wipe and not every time ). Figure it’s just my period coming as I tend to spot days leading up to it. However starting about 30 mins ago I am having this horrible sharp pain coupled with this feeling of tightness in my very lower abdomen right in the center. It come and goes. But it takes my breath away and is sometimes hard to stand up straight. This is definitely not a normal pre period symptom for me. Has anyone else experienced something similar ?
