Back again this month 
My cycles are always 28 days (AF usually starts on day 27 or 28) but today is CD29 and no AF. I have horrible cramps but they feel sorer than the cramps I would normally get, and lots of pain in my lower back compared to normal. I've been symptom spotting like mad - around CD20 (I think ovulation was 12th) I had a weird burning/pulling feeling in my lower stomach.
I've tested 5 times, starting from CD20/8dpo and most recent test was this morning. All BFN! I used 2 clearblue, 2 FRER and 1 cheapie from home bargains. Surely it would be positive by now?
Ive never had a late period apart from when I was pregnant with DC1 so now I've got my hopes up and I know Im going to be disappointed 
Anyone else in a similar boat? Or anyone been late with BFN before going on to get a BFP?
