Is elderberry safe?

cclc • Married 6/13/15. Baby boy 4/30/16 😇 June 2018 😇 October 2018 😇 November 2018. Diagnosed with MTHFR and Factor 13. Expecting our 🌈 in 2/20/20 👶🏻Currently on progesterone and blood thinner injections

I asked my doctor if I could take elderberry in syrup form with my prenatals and she said “wow I’ve never been asked that but I think so?” I took it yesterday but now I’m paranoid that I’m like overloaded on vitamins. Does anyone else take both? Just trying to stay ahead on sick season with a toddler in preschool.
