No visitors after birth

I don't want visitors after birth 7-10 days at least. I fear DH will resist me, at least until she's born, because he doesn't understand what it will be like. He already wants his mom & sister in the hospital lobby against my wishes.

What are your experiences with unwanted visitors?

What are you planning for yourself?

EDIT: I go back to work less than a month after baby is born. Daddy is only taking a day or two off. I will be emotional, vulnerable, and self conscious. i will be learning to breastfeed and cooking, cleaning, and homework since I'm a grad student. I do not feel bad.
