hi i don t know how to tell if im pregnant. my ovulation period was last week n i was having sex no protection and im not on birth control either. my fiance was using the pull out method but i dnt think thats effective and saturday night he didnt pull out at all. sunday morning i was experiencing cramping more on the gasy side then later yesterday afternoon i had a very heavy milky like discharge with a red blood like film to it. today i am spotting n still doing a lil bit of cramping. my period isnt due til next week. what do i do to figure this out? i did start take prenatal vitamins just in case and i was going to wait n see if i miss my period. but im a o neg blood type and if so i need to get a shot. im just wntn answers i guess my curiousity is getting the best of me.
