Is it a chemical ? Help please :(

Dulce • mommy to Ella Ocean Luna. 💕🧚🏻‍♀️ and another tiny human on the way

I took a pregnancy test yesterday at 11 dpo around 3 pm and it was positive , a faint but visible line , I took another one today with the first morning pee, same brand , and it was way more faint than the first one.

So I’m pretty confuse now. I’m having cramps and like a pressure/pulling sensation in my lower belly. Super sore boobs and weird feeling on my belly button.

But since the second test came out more faint and the “symptoms “ are a lot similar to my pms ... it might be a chemical ??
