Yes or no??

Hi all. So basically I am asking if you think I could be pregnant or what's happening with me. Any help would be awesome. Thanks in advance.

So my cycle is usually 30 days and my period lasts 4-5 days. I am now on day 38 and still nothing. Ever since I've used this app my period has always been on time. And 7 days late is really kinda a while.

I am sexually active and had sex on days 6, 19, and 26. We used condoms and he does pull out before he cums, however I am not on birth control.

I did not take plan b or anything like that because I did not (and really do not) think I am pregnant. However it could be possible. I did take a pregnancy test however and it was negative. I also do not feel any dofferent than normal that would indicate anything.

Let me know your thoughts and if you need more info!
