Baby bump vs bloat

I'm trying to figure out it my belly is maaaaajorly bloated, or if it's actually a baby bump. I'm still waiting to see my doctor and my HPTs have been no help (invalid 😐). If I am pregnant, I'm about 10 weeks gestation (or 12 weeks). So please answer based on your own experience. I am fully aware that none of you can tell me with 100% accuracy if I'm pregnant or not.
•My belly is very hard near my pelvis when I stand up, but when I sit or lay down, it becomes squishy- baby or bloat?
•My belly has steadily grown, it didn't become large overnight- baby or bloat?
•Sometimes when I have to pee really badly, my belly does look significantly larger than it is when I don't have to pee- baby or bloat?
Please tell your story! At what point in your pregnancy did you look at your belly and say, "hey! There's a baby in there!"??
