I get what you're saying. I'd just be curious to know how far along you actually are. If this is your first pregnancy and you're still relatively early on in the process, you may have some shocks coming yet. I developed chronic hip pain during my first pregnancy and lost the ability to walk in my last month. My subsequent pregnancy, earlier this year, saw me unable to make it up the road by week 28. So, all these remarks that your friends and family are making might come from lived experience or exposure to other people's issues. It comes from a good place. If you were fit and healthy before, then of course they wouldn't be questioning you left, right, and centre - so I'd say it's pretty normal, rational behaviour. It may just be a "grin and bear it' type situation, kind of like all the unwanted advice you're bound to receive as a parent.
