This is just my opinion as someone who gave birth during 8/2020 and didn't have the vaccine available- I would get the Moderna vaccine ideally several months before conceiving. The mechanism of the mRNA vaccines does not suggest any problems would develop after it takes effect. I didn't have that option due to the timing, but I would have been more cautious about receiving it during pregnancy. I am a physician.
Any intense illness that causes fever can increase the risk of miscarriage and birth defects in the first trimester, and the reaction to these vaccines can be intense. This may not make you feel better, but the tDap and flu shots commonly given during pregnancy don't have any specific approval for pregnant women either as far as I know. We think they are safe due to the accumulation of observed data over time.
The cardiopulmonary changes during pregnancy do make pregnant women higher risk, but like all categories in covid infection, most do fine and have mild disease. As I sometimes tell my patients though, if the 1% is you those stats don't really matter much anymore.
