I know this app is mainly for telling you when your fertility window and when ovulation is . But I had un-protected sex 5 days ago using the "with-drawl" method , and then had sex agien 2 days after that . 5 days ago is when my fertility window started and today I'm supposed to be ovulating . Yes , we did use withdrawal , but he ejaculated on my vaginal opening and we went 2 rounds , (I heard that you could get pregnant from pre-ejaculation on the second round ) I know it's a very low chance of pregnancy , but today I felt different . I just have this over whelming feeling that I am pregnant! It's driving me crazy !! And on top of that gut feeling , I felt sick to my stomach this morning , I have loose stool( diareah) , heart burn , cramps on both sides of pelvis , back pain and unusual food cravings . Sound familiar ?!? I know it's early if I really am pregnant to be showing symptoms but I've done research and moms all over the world have felt symptoms as early as 3 days after intercorse. I need help and opinions , do you think I'm pregnant please help me .!
