Cramping inbetween periods possible pregnancy?

Celeste
These cramps are so different. They are sharp! My boyfriend and i have been trying for five months. I had my period twice last month around the 3rd and 30th which is not normal for me. I have been cramping like this for about a week now and keep getting headaches with it and dizziness. I havent been using ttc kits or taken any pregnancy tests. Has anyone every had this before?
