Mad about being in a bad mood

10 weeks pregnant with baby boy number 3. Me and my husband are very excited and kinda relieved for another baby boy the scariest part is once the baby is here my oldest will almost be four. (3 under 3 😬) anyway that being said, I've been so moody lately, especially with my husband and my 3YO is starting to push my buttons lately too. I don't want to be that moody mama/wife that makes my family unhappy. I take regular prenatal vitamins. Does anyone else feel like this or take special vitamins to help this? Is this something I should mention to my doctor? I've been yelling alot lately and it's exhausting I don't want to stress the baby out. 😔
