Ok.. so me nd my bf have had sex the last couple weeks. Today is the 23rd of july and we had sex on the 6th, 20th, and 21st. On the 6th we didnt use protection the 20th we did and the 21st we didnt. i was suppose to start my period yesterday. but i didnt. i kinda scared but then again there was also a family issue the 21st so there was alot of stress that day. so i also put that into consideration. that it could just be delayed because of stress. He said he didnt do anything. but there is also pre-cum. is there a really good chance of me being pregnant? ive had this scare once before. but it just turned out i was like 3 or 4 days late. i ended up starting. im not really having any symptoms or anything. well i dont think. but if you could possibly give me some tips or just help me understand this stuff more. because im young and i feel that i know quit a bit but i know its deffinately not enough! Please help in any way that you can! much appriciated! Thanks(:
