Unisom while breastfeeding?

I just recently found out I’m pregnant with baby #2 and I’m still breastfeeding my almost 1 year old son. I started taking b6 and I bought unisom but wasn’t sure if I could take while still breastfeeding? I took diclegis when I was pregnant with my son for morning sickness and it helped a ton so I wanted to start taking b6 and unisom but wasn’t sure about the unisom. Thanks in advance!
