So I have a 3 month old. I was just entering my 3rd trimester when lock down hit. My husband and I, and half of our families work either front line nhs or super markets.
I worked from home but my husband (frontline nhs) continues to go to work. We only saw family from the end of the drive once or twice. But it was ok!
I'd had my 12 and 20 week scans obviously by the time lockdown happened. But had numerous and varied scares along the way involving hospital admissions or scans alone, and whilst not ideal - the midwives were amazing and we face timed a lot. If you have a severe reason why you need support if your partner, id ask midwives to accommodate you, maybe the last appt of the day. Plus private scan facilities are letting partners come, as are some trusts.
Prenatal classes, we did NCT online via zoom it was great, the 8 of us mums meet every fortnight for a walk and coffee, the days go to the pub monthly, we whatsapp daily. It's been a godsend. For someone with social anxiety online might even be better for you than face to face.
Labour wise my hubby could only come when 4cm, but to be honest I was that busy being in pain/breathing through contractions I wouldn't have noticed if he were there or not lol. He came when I was 3cm as my waters broke with merconium so I went straight to delivery suit and he joined me there. It was devastating that he had to leave 2 hours after delivery and I was in without any visitors for a few days which was said but meant baby and I bonded loads, we FaceTimed dh snd family loads too. However ladies on my nct group who gave birth in a different hospital had their partners stay over night/able to come for visiting hours. There's a lot of push back against these people bet zealous rules do by the time you give birth could be allowed your partner the whole time.
Baby classes are back up and running. Only difference is smaller socially distanced classes with extra cleaning.
Visiting grandparents wise - we basically said f the rules and had both our parents visit and cuddle babe but with strict hand washing, masks and clean clothes at first. Now it's just like normal and I'll continue as such!
I'd say if you've been trying for 2 years I wouldn't waste another day not trying (I say this as someone who tried for 6m, then miscarried then going pregnant 6m later) because of rules that may or may not be in place by the time you get pregnant plus 9 months.
Yeah it's not been like most people's experiences, and yeah not ideal but it's been fine! Made the most of it and enjoyed the positives (more cuddles for me, less expectation to see others/do things).
I think you're over thinking it. There's no perfect time and things may be this way for a looooong time.
Good luck!
