better not to think so much at this time.
Spotting sometimes occurs because your Uterus is expanding..
Just take note of the quantity of the spotting... if it is getting too much like menses, then go find your gynae again immediately.
for My M/C last june, my bleeding was alot... followed by very bad cramps, on and off contractions like giving birth like that...
THink about it... even if one's tummy stopped growing, I dont't think it will Shrink overnight... the only thing that will cause our tummy to shrink is the Gas/Wind in our Body.... overnight.... and during Pregnancy/AF, will have gas in our body one.... Last Week. I was having alot of gas in my body such that I could not wear my pants on at all... I thought it was because i ate too much durian... but surprisingly, this week, i can fit into the the pants again.... because the gas were slowly released out.
As for MS symptoms... Not everyone will feel the MS symptoms everyday... some felt it this week, and MS symptoms gone next week but still manage to have healthy pregnancy...
Continue to be good, eat your antai yao, supplements.... go for brisk walking under the morning sun, Sleep early.
i believe Gynae prescribe progesterone pills for you?
