I had my last period on August 31-September 7th.
I had sex on September 14th and 21st; he stuck it in without a condom for not longer than 10 seconds both times, and then we had sex with a condom.
On September 22 I had blood in my urine, but i have noticed that it burns when I pee and I have to go pee a lot. Could this be implantation??
Now I have cramps in my stomac and I should have started my period.

Do you think i'm pregnant? or a possible Urinary Tract Infection be delaying my period?
