Thanks for your query,
Yes, you are right , these symptoms are related to pregnancy
. Actually gravid uterus
gives pressure on illiac veins more on the right side due to dextrorotation of uterus. So there are increase chances of development of varicose veins
and deep vein thrombosis
. In your case , it was already there and have became more problematic. So take more rest and precautions.
Take care ...
Hope it helps you..
