Im so sorry for your previous losses and im sorry nobody was available at that time to give you some comfort.
You have 3 children which is amazing! It shows your body can do some wonderful things, you'll find everyone here has gone through the exact same thing, whether its 1 loss or multiple losses. Its never a nice thing to go through and you do have that anxiety throughout pregnancy although the anxiety changes when you get to a certain point.
You'll have seen things mentioned about anxiety over early pregnancy, scans ect.
Just know you are not alone in this journey, ive had 3 recurrent losses before this pregnancy and gosh it was so hard!!
With this pregnancy i barely had any symptoms, i went for an early reassurance scan at 7 weeks thanks to my midwife. I had to fight to cancel my holiday to rome because i would have been 7 weeks at the time of flying and ive always suffered losses when i believed i was between 7 - 9 weeks pregnant, so we decided that was best for us.
There was a lot of tears, sleepless nights, and overall anxiety to the point i'd be a stressed little hermit going to work and saying to my colleague what if..
Self care, and keeping yourself busy will get you through this tough time!
Gentle congratulations on your pregnancy, we will all try and help out as much as we can, but it may be worth speaking to a GP about your MH and getting some help before you are able to see a midwife x
