So i ususally have a fairly regular period 28-30 days apart. My Husband and i have unprotected sex. usually pull out meathod (i know i know) anyways i havent had any problems but he came in me almost a month ago and i've been experiencing pregnancy symptoms.. i.e. fatigue.. headaches.. breasts are soar.. etc. even my stomach hardended a little and i've gained a little what looks like fat pouch .. but it's still fairly solid.. anyways my period came around normal time.. but it started out very light which is unusual for me and there is no clotting.. i've been having cramping for the past week but no period til today. it's just strange to me.. what do you think?
