Anyone know how long it takes for calcium to actually absorb in your body and if it's something that needs to be built up over time to make a difference in your nutrient levels? (Sorry that is a long winded question.) When I conceived DS2 I was drinking high fat milk by the gallons (per IG). I was trying for a girl but got a beautiful boy. This baby was a surprise and I was consuming very little calcium EXCEPT for the couple days around ovulation. I drank some brandy with egg nog. Hence the reason we had an oopsie. Lol! I just read that egg nog has more calcium than milk. I know what's done is done but I'm just obsessing. My ultrasound is tomorrow. Eek!
