Alright, last month in july I got my period on the 12 to the 16 I had sex on the 18, 20 and on the 24 I was supposed to have my period on the 12 but got it on the 15of aug and it ended on the 18 it was kind of light. On the 12 of aug I also had a blood test and it was neg and before that I did at home tests that were also neg. I have had lower back pain, cramps and slight headaches. I do get nausiated but not to the point of throwing up. I've made a doc apt for the 28th of aug. I was just wondering what do you think my chances of pregnancy are?? Should there be any really obvious signs of pregnancy right now?? I would really like to know if you think I could still be pregnant?? Thankx lee
