Milk craving.

Hey mommas! I'm brand new to this app but love it so here's my first post... My husband and I are trying for baby number 2 and have been for two months. I am 12 days away from my expected period and we've had sex every day since my last period ended. All of a sudden I have this crazy (but firmiliar! Had the same thing happen during my first trimester last pregnancy) milk craving. Just myself have had 2 gallons in the last 4 days. Let me be clear and say that aside from my last pregnancy with my daughter, this is very unlikely me! I have maybe one small glass of milk a week normally. Ive also started taking prenatals 6 weeks ago to prep my body for baby #2. Is this a sign of my body creating another body? Is this from my prenatal pills? Pregnancy? Please, if anyone else has experienced this let me know! Don't want to get my hopes up, but it's hard not to! 😊
