Cramping

I try not to get too excited anymore or to focus on symptoms before I miss my period. However, it's cycle day 25 and I believe 5-6 DPO and I'm experiencing bloating and a mixture of dull aching and sharp pains for about two hours this morning. The location was very very low abdomen, right in the center around the uterus. 
Anyone experience this either way? Period or pregnancy? I have a 33-34 day cycle, so it's not menstrul cramping yet. I usually don't have those until day 31,32.
