Scared of miscarry

Joy

I am so afraid that I’ll miscarry. I miscarried twice. I feel some soreness in my breast sometimes it is extreme other times it is manageable. I am 6 weeks and 2 days. I noticed the Montgomery tuberculosis on my breast are decreasing. I have my first ultrasound next week. I am so afraid. Anyone else notice a decrease in the Montgomery bumps on their breast? Other symptoms I have is slight bloating and slight nausea.
