Getting pregnant at 34

Personally getting pregnant at 34 has been exhausting, I work a full time job, commute 2.5 hours total a day, cook dinner, clean, have to pups (one being a puppy) and an amazing and wonderful husband but having sexual more than twice in one week is work!! It takes more energy just to get in the mood than it does to take my pup out to pee at 2am in the morning. I laugh to myself because my husband and I are affectionate and we have an amazing marriage but sex is work and it’s been the most frustrating part. My doc told me to have sex every other day during my ovulation week, I laughed at her... seriously? I can’t even get to the gym every other day. Let she reminds me to have fun with it, enjoy the time, it’s the best part of making a baby.... haha I’m dying because I am sorry but how can you enjoy sex when you are obligated to have it?! I can only buy so many sex toys, and lube is out because it can block the sperm. Is there some kind of pill I can take to get us in the mood and give us energy for a marathon of sex? Haha.
