If a girl doesn't suspect they are pregnant, they will never take notice of it, thus the only way they can take notice of it is good signs. The girl I was with has irregular periods so missing a period doesn't count.
I am just anxious about the existence of risk for pregnancy because of a unprotected sex encounter with a girl. I am pretty sure she will not take a pregnancy test and I do not have contact with her anymore because we ended in bad terms and she blocked me in places where we used to chat. When do you think will a person most likely realize that she might have a baby growing inside of them? Since pregnancies last for 9 months I really want to weigh the probabilities as time goes by this will lessen my anxiety. For instance after a certain time if she still does not contact me, I can feel safer because chances are she does not have a need to.
I had unprotected sex on December 18 with a girl and used the pull out method I know it is risky, but it was a one time thing and I don't plan on doing it again ever until I get married. I tested for STDs already and clean of HIV, Herpes, Chlam/Gonorr, Hep B, and Hep C. The girl I had sex with has an irregular period so i'm hoping that she has less than 12 cycles a year. She also had bacterial vaginosis during that day so I wonder if the unstable pH of her vagina during that time will restrict sperm (if any was present) from conceiving an egg (if any was present).
The thing that worries me is that I was close to the point of no return when I pulled out and let the sensation calm down. I also know that before climaxing, there is a chance a very small amount semen can leak out, and I continued on until the point of no return and pulled out completely before ejaculating. Given that any did leak out, I am hoping that she is not in her fertile window. Given she is fertile 6 days out of her 28 (to 40 day cycle?), she has a 15% (assuming a 40 day cycle) to 21.43% chance to have to be fertile during the time we had sex and even if she was ovulating, she only had a 33% chance (upper bound of the statistics) to get pregnant when having sex on the day (I believe the figures meant if you ejaculated on the girl during ovulation day or a day or two prior). Making my chances of getting her pregnant of 4.95% to 7.07% chance on a random 1 time occurrence. But I did not finish in her and my concern is the leak of semen (if any is present; which in my head is a near 50/50 chance of happening). With this, can I assume I have less chances of getting her pregnant? I know it is risky and people keep saying that there is a chance with this exposure, but I just really want to weigh my risk.
My parents had unprotected sex for more than 20 years after I was born and I know they just pull out (I also know they still do until now because I found some lube and my parent's door is always locked. Disturbing but unintentional). So given they did that over many years, I think it's not that easy to get pregnant when pulling out?
