Hi @Viletta, hope you are feeling better, I'd say maybe ask your midwife about being tested for anaemia and GD as I did the same, my sister was anaemic during her pregnancy and told me the symptoms can be easily identified as "just being pregnant", but it's really best to check. (reminded me of early pregnancy symptoms being the same or similar to PMS..).
Also got a leaflet about pre-eclampsia that can occur during pregnancy and is more common that I thought (I also have low BP and thought it automatically means I am not likely to have that, but my friend unfortunately disapproved that with her own experience).
These are not major-major issues, only if you don't know if them, so I agree with @Wimbledon1 that we need to measure up the risks of having a condition unnoticed VS attending appointments to get checked out and might catch CV-19. Going on for months with no check up is scary for me too, last time I had my blood taken was in March.
