I'm soo anxious all the time can't wait for this pregnancy to be over even though I'm only 22 weeks! 12 scan showed fluid around baby and only given 10% chance of survival. Had cvs came back all normal. Had 20 week scan fluid all gone Normal scan! Obviously soo happy but can't get away from this dreaded feeling that something is not right he doesn't move as much as my other 2 did. This has affected me soo much that im on meds but aren't right so going on to different ones but takes time! I have an 21 month old and 10 month old which are my world. I just feel soo alone even though I have my husband but is working, don't have any friends and only mum and sister but have their own lives. I had a premature birth last time and I'm soo scared of it happening again! or giving birth then baby dying soon after I hate feeling soo negative!!
