I had sex about 2 weeks ago with my boyfriend and we used a condom. I should have started my period about 3 days ago but I didn't. I'm usually late... i.e. 5 days or something's I miss it completely but I'm still worried. For the past few days now I've been having lower back pain and real bad gas, both what I have right before my period but it has yet to come. I've been very stressed out not only do to this but also because I'm leaving the country in the next week and half. I've also haven't been eating because I've been so nervous and also staying awake all day. Every time I think about being pregnancy all the symptoms that I have read about start to act up but when I do something and occupy my mind they go away. I'm not fatigue or my brest aren't tender but sometime I feel sick to my tummy but that goes away when I eat. I'm still very nervous and tomorrow I will be taking the HPT is it just me being extremely nervous or stressed out or may I be indeed pregnant.

I also did not have sex until the week after my fertile week, I use an app on my phone and it said that I'm late by 3 days. It has been wrong for me a lot of time because I'm so irregular. I've been over 20 days late without having sex, before. I'm also very new to having sex. This my second time and the other time was a year before this. Could this also have a fact on it?

Don't waste money on pregnancy test this early.

Also stop reading so much without context. Almost all the signs you are talking about happen in the 2nd and 3rd month, not two weeks after sex.

Condoms have a 3 to 18 percent failure rate, so of course pregnancy is a option.

You have to wait till you are at least 14 days late, to even start testing, so just calm down and wait.

All right thank you. Do you think because I'm so stress, maybe that's why it's late?

Very likely, stress really have issues on this
