Faint positive test at 2 days late

I took a test last night, I know youre supposed to do it in the morning but I figured it would be stark negative. Immediately as it was going across it popped up. Its faint and hard to get a pic of, im gonna wait a few days and retest if af hasnt started yet. I didnt even realize my period was late. The only weird thing that has been happening is my boobs are very very warm to the touch and swollen and hurt a lot. I've been pregnant before and miscarried multiple times and never had my boobs do this. Even my fiance can feel just how abnormally warm they are. At first I thought maybe I somehow have an infection. But there is no redness, and the warmth comes and goes.
