First time goat Owner having kids

I recently purchased 3 pregnant pygmy mix does and was told the buck got out of his pen and the does we're probably bred. I am most certain all are bred but they are driving me nuts thinking they are going to kid. Blossom is a FF and started leaking very small amounts of her plug about 3 weeks ago and has been bagging up about the same amount of time. She is very puffy and her vulva has turned a darker pink. The kid is wild and crazy like her mom constantly kicking and moving. She has sunken in sides for about 4 weeks now. Also she did not start showing in her belly until about 2 weeks ago but I could see her kid move longer, her stomach is very small next to the other does. Buttercup has done this once before and is very wide. She also has a very puffy vulva but hers has an opening in it about the width of a pen. Her whole back end has turned a pink color with her vulva being pinker then the rest. She has also been losing small amounts of her plug for about 2 weeks now. She has been bagging up about 3 weeks now. Her sides do not look sunken in. Her ligaments seem to be dropping. Her kids are not like Blossom's they move around occasionally but they are not wild. Bubbles is our last girl and she is carrying her kids more round then wide. Her vulva is puffy and turning brighter and has about the same size opening as buttercup. She has been bagging up about 3 weeks now and her sides are sunk in. I occasionally see her kids kick but not often. She stretches the most out of all of them. Also I can feel ligaments on all of them. I was hoping maybe I could get some insight on how much longer this could be. We got the goats in the beginning of October.
