I had unprotected sex a week before my period and still had that period. for the past couple of weeks i've noticed that i have been urinating up to 10?

Not pregnant but...: If you had unprotected intercourse 1 week before period and you got your period on time- you are unlikely pregnant. But frequent urination may be sign of possible urinary tract infection . Very common when sexually active with new partner " honeymoon cystitis" . usually there is more symptoms to it. As discomfort etc. I recommend to have urinalysis done and pregnancy test in any clinic.
