line progression?

Mallory • baby b 6.6.18👼🏼 rainbow baby due 4/8/19🤰🏻💙💗🌈

is this good line progression? i had an early MC in june. i think my line is getting darker a lot faster this time. when i went in for my first apt he said my hcg was on the lower end, i ended up MCing about a week after that. i’m so scared it’s gonna happen again😩
