FTM- maternity leave advice needed 💙

Hey mamas! I’m 39 weeks and due 02/11. I am a full time nurse and have continued to work up until this point, however I had to call out today because I have NO energy. I’ve started having very random period cramps and an increase in soft stools. I’m taking twelve weeks off for leave, but I want to see what you other mamas would do..

Should I go ahead and listen to my body and take leave now, or should I stick it out. I walk at least 5 miles when on shift and it’s exhausting me mentally and physically but I’m afraid I will go past my due date and will be missing out on time with my little man if I take leave too early. Idk what to do.
