HELP PLEASE

Hi everyone!! So I started my last period on December 21st. My period ended on the 25th and my boyfriend and i had sex on the 26th. We used a condom and in addition he pulled out before finishing even though he had a condom on. eve says that i didn’t ovulating until the following week after that. I am now a little over a week late for my period. I took a pregnancy test on January 25th and it was a strong negative. I’m taking another one Thursday. Would you say this one tomorrow should be a correct negative and not false? I also have no pregnancy symptoms. If i am pregnant i am almost 6 weeks.
