hmmmmm, there are few if any analgesic herbs that we know are safe during pregnancy. I would think external heat (heating pad) or a topical CBD oil with some analgesic essential oils would be the safest approach. Internally perhaps a tea with Chamomile (2p), Rose Hips (1 p), Black Haw bark (1p), Ginger (1/2p) and Peppermint (1/2p) might offer some modest relief, but as with most herbs there is controversy as to the safety of some of these during pregnancy.
