To test or not to test

I’m officially a week late, I had extremely light spotting one day, then it stopped for 2 days and then spotted very lightly one more day. It’s not even enough spotting to see when wiping, I stuck a clean finger up there and there was very light pink. Boobs are super sore, almost warm to touch, nipples are erect

most of the day not only when its cold and I’ve been super supppper moody for the past few days I feel so angry and sad at the same time it makes me feel crazy. My SO and I have been TTC for 4 years and we’ve had 2 miscarriages, as anxious as I am I want to take a test, he’s more of a waiting person he hates to see the negative.

Do you ladies think there’s a bun in the oven? Should I sneak and buy a cheap test w/o SO?
