Cordyceps for pregnancy

Hello mummies, anyone taking cordyceps during pregnancy? I’m at 21 weeks now, and my MIL insisted that i take cordyceps for my baby’s immunity, but I kinda worry as my pregnancy is not as smooth as others. I had 2 bleeding so far, luckily baby is fine. Basically I’m kinda scared of taking chinese meds 😅 Any mummy can advise please? Thank you!
