I'm so confused!😩

So my hubby and I had sex once this last cycle, right when I was ovulating. I'm now five days late and AF isn't making any kind of appearance. I took a FRER test when I was 2 days late and it had a faint faint pink line, I took another one the next morning and it also had a faint pink line. I bought a pack with the FRER line test and a digital, waited until I was 4 days late and took the DIGITAL and it said NO. I took an ovulation test directly after and it was positive. I took another line test today and it had the same super faint line. I took another ovulation test also and it is still positive. My cervix is high and soft and my CM is thick and white. I just don't know what to think! I just don't know how I could have gotten pregnant from one time of having sex (he pulled out) but I've been regular with my period since it came back after having my daughter and this is he first time I've been late at all. I'm so confused 😩
