Symptoms and Negative test

So I got off of my nexplanon implant. My periods have been irregular and weird. I’ve have crazy pregnancy symptoms. This would be my second baby, so I remember.

The symptoms are:

Sore boobs

Feeling gross in the morning

Hating foods I love

Peeing all the time

Getting super pissy or sobby for no reason

Discharge ranging from egg white, to clear, to white

Headaches

Backaches

Being super tired

So keep in mind, we weren’t trying. So I’ve never used an app like this and I’ve never truly tracked anything.

But according to the app, we did it (withdrawl and once unprotected) like 3 times during my fertility window, twice before (and from what I understand sperm lives in your body for like 3-5 days.) so I feel like the chances of this being real is high. ESP cause I wasn’t planning a kid, so it’s unlikely that this is a hysterical pregnancy.

The app predicted that I was supposed to get my period today and didn’t. So I took a test and it’s negative.

Does anyone have any advice or comments about this particular situation? Can anyone guess if this is legit or not? ‘Cause I’m confused. I want this kid now that I think it may be here. Anything would be helpful
