Help!!!!!

I recently found out I’m pregnant again. I’m possibly 6 to 9 weeks pregnant. I actually have my first ultrasound Monday to figure out my due date. But today I’ve noticed light brownish tint only when I wipe along with very mild cramping. With my son I spotted dark brown once at 5 weeks but now I’m worried since this time around I didn’t anticipate to get pregnant. I’ve been so scared of miscarrying. I’ve been testing daily and the test like keeps getting darker not that it matter but for my sanity while I wait for my appointment Monday Does this look normal?😥
