Did this actually happen?

I have been feeling off for the last 2 weeks, super grouchy, headaches, sore back/hips, the last few days my breasts have been swollen and sore, so I decided to take a test this morning, first response digital, my period is due tomorrow and a +yes popped up! I have two kids 13 and 5, with BOTH kids I had extreme morning sickness pretty much right out the gate which was always a tell I was pregnant, this time nothing, a little nausea but nothing substantial, according to my LMP I’m 4 weeks pregnant, My husband and I have been going back and fourth if we want another, I’ve had three miscarriages in the last 4 years, I don’t know weather to be excited or not, we pretty much said we were done trying and content with our two kids. Is it a good sign I got a positive on a digital before my period? Any advice appreciated!
