6 days late & confused! Please HELP!

K

Hi Everyone, I'm new here.

Ok I'll start off by saying I went to the hospital and got a blood pregnancy test as well as urine and both were negative.

But here's the thing.

I'm not on B/C and have been living with my SO for almost 3 years.

On August 29th, 30th or 31st was the last time we had UNPROTECTED sex and so we were going based on my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> that said I ovulated 8/21 - 8/27 but I downloaded this <a href="https://play.google.com/store/apps/details?id=com.glow.android">GLOW app</a> and I entered all my info including my periods starting January 2015 til August.

My last period was August 12th.

This app is telling me I ovulated between 8/27 - 9/2 and I did have some very light pink spotting on 9/1.

If this app is correct and I did infact ovulate 8/27 - 9/2 then that means we had sex while in ovulation window. So IF I am pregnant would it had shown up on blood test that was done on 9/14?

Or should I go with what the hospital said on the 14th that is negative?

I been having really bad period cramps for 2 weeks, nausea, dizzy, sore/tender boobs, painful nipples, lower back pains, sensitive smell ect. Typical pregnancy symptoms and here I am 6 days late and still no period yet negative blood pregnancy test that was done 2 days ago.

I appreciate any thoughts as to if there's still a chance I could be?
