High sex drive while pregnant?

Kennedy • Married to my soulmate since 7.4.2020!💍💞 We have a 4 year old son, who took a year and a half to conceive! We are expecting baby girl March 11th 2021 after 2 1/2 years of ttc with fertility treatments 💖
Before I got pregnant I had no sex drive what-so-ever. But now that im pregnant my fiance can't keep my hands off him! Im always so tired and it makes no sense to me. Everyone else that I've heard had said they have no sex drive now that they are pregnant. Is this normal? Lol
