So nervous

Because of 2 previous miscarriages and 1 ectopic, my dr had been monitoring from the start. She did an early US and said she is 99% sure the pregnancy is in the uterus. Tgays wonderful news, but....my hcg levels are not rising very well. They were 94, 296 48 hours later, 986 4 days later, then 1500 something 44 hours later. She said she'd like to see a 60% increase and mine are right at the bottom edge of that 60%. Also, after my transvaginal US yesterday, I've had tiny brown discharge when I wipe sometimes. I also started progesterone suppositories last night because that came back at 9.5. Prayers please. These numbers just aren't great 😥
