13 weeks and sleeping all day

Elle 👼🏼👼🏼🤰🏻due 13/12/19

Hi all I’m 13 weeks and I work pretty hard Monday- Friday and often do over time. I don’t really have any other commitments (other than social, my poor friends have been cancelled on numerous times) but I am SOOOO tired this weekend. I slept around 16 hours last night, woke up this morning for around an hour, had breakfast and fell asleep again. Just woke up after around 3 hours and I want to go back to sleep again.

Is this normal??? I feel like such a sloth 😣
