Hi lichelock
i'm in my 9th week and about 2 weeks ago had severe cramps and bleeding...But at the emergency room they confirmed that the embryo was still attached and my cervics was closed...Since then i've been at home lying around and taking it easy. I also have a ovarian cyst but apparently it doesn't cause any problems for my pregnancy ...The cyst is due to an overstimulation of hormones. The doctor prescribed me utrogestan...It's a progresterone medicine that stops cramping and helps against miscarriages.
Even if the umbiblical cord is coming loose, it can reaffirm its attachment by your staying calm, lying down a lot and sleeping specifically on your left side..Apparently this position helps the embryo breathe better and thus take up more oxygen and thus breathe stronger and have a stronger heart beat!
In the first trimester we have a high level of progresterone and this also makes the embryo sleep more and thus have a slower heartbeat...Any way at 7 weeks, the little one is still muniscule (mine was only 12 mm at 7 weeks) and nature knows what its doing (i hope;-))
in terms of throwing up...I'm not throwing up but can't stomach water!! I'm seeing my specialist tomorrow...And getting a 3rd u/s so hopefully he'll give me advice for the heartburn and nausea...
I'll keep my fingers crossed for you two because I know how it feels to worry and not know if everything is fine...
