Sounds totally normal Charlotte. IVF can take a toll on so many things: bank balance, relationship with partner, with friends and family, body, emotions and head! There are meds to deal with, appointments to juggle and of course stress over whether it will work or not. (but you know all that)
And our DHs deal with it in different ways to us very often. I can totally relate to the being able to control PMT emotions and wanting to be able to control emotions when on meds. It is just so unpredictable what they do to you.
sorry, can't help much but wanted to tell you that you ARE normal. And good luck.
