Currently on CD31 and getting BFNs. Last cycles were 25, 27 and 29 days so definitely late on and no signs of AF arriving (usually spot a little beforehand). Cycles usually regular 26-28 days but since periods came back in June following the birth of my LO they've been steadily decreasing in length back to normal.
Only had sex once (with a condom) but it was bang on fertile period. You guessed right - it was Valentine's Day lol!! So it is quite unlikely I'm pregnant.
Have had mood swings, back ache and hip pain - the only other time I've had hip pain like this I was 6 weeks pregnant. It's like my hip 'drops' as I'm walking along and it's excruciating!
This not knowing what is going on it doing my head in a bit but also I go on holiday in two weeks time so would like to know before then (so I can take full advantage of the AI bars 
).
If I still have no AF and still having BFNs what do I do? Would the doctor's even entertain blood tests at only a week or two late?
(Ps. Toddler is breastfeeding same rate and I'm not stressed about anything so nothing obvious to affect period!)
