When i was preg with DS he was due in August so i missed out by a couple of months but DH got to celebrate fathers day so i told him i wanted a present cause i was doing all the hard work so he bought me a footspa...(which was heaven) and a too cute mother to be card lol.
This year was really hard as my mum passed away on the 1st May and i couldnt bear to go out and see all the people being happy with their mums... so DH took DS and myself out for lunch and a later we went to the movies. (the only difference was we celebrated on the saturday)
So i think you should get a lovely card at the very least
