No period for 31 days!!!?

ok so I had sex with a condom on april 8th and started my period on the 25th of april I bled for 7 days.. then I started my period again on may 27th and bled for 4 to 5 days but I would stop in the middle of my period for a few hours then it would come back lighter and lighter as they days went by.. no period for june now its july 1st and still no period so its be about 30 or 31 days without my period.. Im cramping though and having mild sharp pains on sides of stomach, very bloated, and I've been eating a lot! does this mean i might be pregnant? I dont think the condom had a leak or anything..
