Ok so last few cycles have been in between 21 and 35 ish days (came off pill in September). Last cycle was 29 days - began December 22nd.
We have dtd ONCE since then - in the v early hours of New Year's Day 
This Thursday will be 14 days since then, so in theory a pregnancy test will be accurate. However, if this was a textbook 28 day cycle it'd be like doing a test 4 days early 
I think pregnancy is unlikely, as we dtd too early. DH, as usual, has got his hopes up and thinks we're in for a chance as I keep snapping and crying randomly (usual PMT signs for me!). Have also put in weight but that must be due to Christmas over indulging?!
Anyone care to advise?!
