Should I take 2nd dose of Covid 19 jab at 14 weeks?

I didn't know I was 4weeks pregnant when I had my 1st covid19 jab.I got a slight fever 2 days after that. Luckily baby was okay. I'm thinking whether to have the 2nd dose at 14 weeks. My doctor told me to wait after 14 weeks though. Did anyone had their 2nd jab after 14wks? Please share your experience. Thanks.
