Why am I so tired

Tia

Holy exhaustion! I'm only 7 weeks and I'm so tired. I have a 3 year old that hates watching me nap. Omg how am I going to go 7 more months + newborn stage. I'm trying not to freak out about this. I don't remember being so tired with my son. Babies are blessings, they really are but this'll be my last pregnancy for sure. Thankfully we agreed on this before I got pregnant but I have 0 doubt after this
