Brown discharge on and off

Hi mummies, I'm currently 7 weeks and second pregnancy. I previously miscarried at 21 weeks last year. This pregnancy around my 5th week i saw brown discharge on my liner about 20cents size. I have yet to go for my first appointment then so I called the clinic. Doctor did a vaginal scan, saw a gestational sac. Baby was very tiny hiding at the far most corner of the gestational sac. Doc said seems like a miscarriage is on the way or a threatened miscarriage. That was the only brown discharge I had. There was a little brown clumps too when Doctor removed the vaginal tube from below. 2 days later I had very light brown discharge. Also very tiny spot. Doc gave me progesterone pills. Take 2. 2 times a day. I've been taking it. Currently having severe food aversion. I can't seem to eat anything or keep anything down. I feel very nauseous. Not much vomiting but super nauseous. Everyday I'm worried. My appointment date got pushed to 2 weeks ahead. I have a toddler. Super active and clingy. He wants me to carry and I really feel so scared to carry him too. And that makes me feel so bad and terrible. Has anyone had brown discharge at 7 weeks?
