Please, try to stay calm as much as possible.
I have now 8 months daughter. She was born here. I had very had emotional pregnancy.... At first, my doctor said at 6 weeks that my baby is too small, and it is possible miscarage again... At 8 weeks I had some heavy bleading... A lit part of uterus just was hurt (then I took on my hands my 2 years old :( )... After that 2/3 pregnancy I was told that it is 60 % miscarriage... They did lots of tests to me... All of them were coming positive (meant possible diseases), but then they did second recheck, all seemed alright. They started to tall me since 22 weeks that I will deliver any time!
I cried a lot. worry. read lots of on internet...
And finally my baby needed induction at 39 weeks! As I was too tired psychologically!
And final: I have super healfy, active and happy baby!
And don't read, till you will have 100% results. it is not worth to worry. I know how it is hard not to do it.
Hope you and your baby will be fine.
good luck!
