How long can i store my pee??

I’m 21. I had a daughter In 2019 and twins back in September of 2020 (the twins were planned )

Me and my husband didn’t want another for 2 years and my chance of twins again is high.

But on new years we both got stupid drunk celebrate and i didn’t remember anything except us having sex. (My parents were watching our kids for us)

We realized the day after that he finished in me and we weren’t worried cause my period was due two days after New Years.

We use condoms all the time however two drunk people definitely don’t make the best choices lmao

However i had bad one sided cramping that night and i never got my period so i am thinking that i ovulated on New Years which means I’m definitely pregnant. (I’ve gotten pregnant the first cycle with both pregnancies) ...

Anyhow so last night i was cramping super bad and thought for sure that my period was coming but nope. Woke up to nothing..

I’m going to take a test today even though it may be too early. But i was wondering if you can store your first morning pee for testing ? I’ve never had to do this so I’m oblivious as to if you can or if it affects the results.

Here’s our Twinkies who were born sept 11th
