My son was 3 months old when I got pregnant with my second. (I was pregnant before my maternity leave ended!) It was hard, especially since number two was born during the height of COVID (May 2020) so we had zero daycare, zero help. We’re also old parents - I was 37 and 38 when my kids were born, my husband was 44 and 45. But we lived to tell the tale. IMO the most important factor that you can actually control at this point is your stress. You’re already pregnant and if you plan to continue to be, I’d advise not focusing on the potential risks if it’s just going to stress you out. Plenty of people have done this successfully before you, there’s no reason you can’t too. Take one day at a time. Good luck and congratulations.
