Got covid in 1st trimester and so high risk now? Why?

[SunnySideUp2020]

So I had covid in week 9 of pregnancy.

Now my gynecologist told me I will have a growth scan every 2 weeks from 32 weeks until delivery because of this. As he says there is a risk of placenta failing.

It's the first time I hear this...
I am in Switzerland but would be interested to know if anyone had been through similar?

This is my second baby, first one was last year, straightforward pregnancy.

Not heard of this stall and no medical evidence of this that I can see. I think at the start of covid there was something around extra scans but not any more as there was no evidence to back this. I had covid in my first trimester and was not offered anything extra / seen extra stall etc (UK). However, it's always nice to have extra scans and see baby!

Hi @SunnySideUp2020 if it's from 32 weeks then that's pretty standard here in Germany too.

We have an appt (with scan) with the gynaecologist (frauenarzt) every 4 weeks throughout the pregnancy, plus the Feindiagnostik (detailed, longer) scans at 12 and 20 weeks in a more specialized centre.

Then from around 32 weeks we see the Frauenarzt each 2 weeks until delivery, possibly even every week at the very end. Always with a scan.

Nothing to do with COVID as far as I'm aware. And that's just with the standard state insurance, nothing extra to pay.

I had covid when I was 7 weeks and not been told anything about being high risk in 25 weeks now I’m in U.K.

Im in first trimester with first baby so limited personal experience but my midwife said to contact her if I got Covid at all as it would mean more scans etc. I think it varies even by area within the UK as people I know at a neighbouring hospital have had different advice on this.
My understanding of the (limited) medical literature on this is that Covid infection causes microthrombosis (tiny blood clots) which can occur in the placenta just as in the lungs. But placental involvement seems fairly uncommon (maybe 5% of pregnant women with Covid).

My first thought was that they were worries about Covid Placentitis, but I think that's something more to worry about later in pregnancy, not at 9 weeks? Strange.

Thanks for all your replies.

I guess it depends on the country/area. But i think it's what some of you mentionned about placenta etc...
I am not complaining. Would rather have all the checks but given how many people had covid in pregnancy I found it odd that I had never heard it before.
