Late September wedding. WWYD?

[Stingeray]

So our wedding is planned for late September. Most things we have already paid for are moveable so we could postpone and that would be absolutely fine. The problem is that I am in my late 30s and we had planned to try for a baby straight away. So our options are:
A)keep the date knowing it might be cancelled or made much much smaller. DPs mum is in the shielding group and we wouldnt want to go ahead unless safe for her to attend.
B) postpone til next year (apparently April and May and the summer are very very full already for wedding venues due to the postponements and we would likely have to change venue and lose our deposit) and put off TTC
C) go ahead and TTC soon and get married while pregnant if we are successful(would need a new dress)
D)Go ahead and TTC soon and if successful wait til the baby is old enough for us all to enjoy the day and me not be breastfeeding anymore (I would be 40 by then and to be honest dont want to wait that long)
E) some other option I haven't thought of

I do realise this isnt a huge problem in the grand scheme of things and if we come out the other side of this pandemic financially stable and with all the people we love healthy we will consider ourselves very very lucky.

A. I wouldn’t want to be pregnant before I got married.

A. I would keep the wedding date and if necessary scale it all down, you could just go to the registry office (perhaps with mums as witnesses) and have a family meal afterwards. Then have a big celebration when possible.

I wouldn't delay getting legally married in the current situation and give your age I wouldn't delay TTC either.

E. Get married in a registry office now and try for a baby when you want. Have a big celebration later next year when everyone can attend.

^or this (although i think even registry office weddings are not allowed atm?!)

leave getting pregnant for another couple of months at least, not ideal in the lockdown with coronavirus cases not dropping.

get married when you can at the registry office (you can't at the moment) and do the party some other time.

it would be sensible for the government to allow civil partnerships, as they are ceremony-free and so could presumably be done over video with forms filled in online. That would give the legal protection and you could always convert to a marriage later.
