i am not sure if this advice can help but during my pregnancy i suffered from mood swings and it can take something little to upset or irritate you but you have to remember that your body is under a huge amount of stress and your hormones are out of balance ITS NOT YOUR FAULT. and when you feel all knotted up it is a good idea to go for a walk (predictable i know)or do something that involves making you happy. if you are happy the baby is. during my prgnancy i enjoyed prenatal yoga and that truly helped. But don't forget the bf making him happy makes you happy and he will do the same. hope this has helped x
