Let the tears flow! I have learnt that there is no point in fighting it DH only has to look at me the wrong way and I'm howling. And I'm not usually an overly teary person - emotional yes, but not often with the tears.

Like the other ladies said, just watch out for a change in how you feel generally and if you're down more than up then it would be a good idea to talk to someone about it. Otherwise, it's just those damn hormones
