3rd baby Indent?

I will test again later because I just can’t tell. My periods are super irregular so waiting to miss it isn’t an indicator. I’m about 9 or 10 dpo. More than anything I want to know to make sure I’m healthy and drinking water. This one and the one from yesterday has a line but I can’t tell if it’s pink. Super faint. It’s my third so the reason I thought I’d test because I’m peeing like crazy which I never do, sore boobs, and nausea with cramps. None of which is indicative of a period cause I’m so irregular. Help please!
