On January 14 me and my gf were messing around and had oral sex. Before I left I rubbed her vagina with my hand. I'm pretty sure I didn't have anything on my hands. We are worried about the chance of pregnancy in this situation and have not fooled around since. She then got her normal period on time on February 2. Since her period she has taken 9 first response pregnancy tests which all have been negative. The last test was this morning February 18 and was also negative. We have doctors app this Wednesday February 20 to take a blood pregnancy test, will this be accurate? She feels normal with no symptoms, thanks for all your help!
