I'm 13 weeks pregnant and this time my hormones are out of whack. I'm hyper sensitive to the point where I overreact to things my SO says (although at times hes thoughtless with his phraseology) and where I become very mean and nitpicky. It wasn't until today he told me he didn't want to be around me for awhile because I never let him relax and am on him that I was like whoa. But I find I get so mad and am so irritable and tired once I get going I can't stop...then we BOTH get mean. Help.
