Cramping before bfp?

[Lookingforadvice15]

This is my 2nd month ttc #2. AF due around 11/12th Feb. Tested today at 8dpo (stupid and of course bfn) today i have been getting cramps, back pain and twinges.
However last month (1st month ttc since coming off the pill) i had the exact same symptoms at around 8dpo, cramps, back pain etc and was more or less convinced i had caught first month trying.....then af showed up 7 days later!!
Im now starting to wonder if its going to be the same senario this month. Anyone get cramps before bfp? Or even get cramps around this point letting them know they are out?

Oh... The reason I actually started reading this thread is because of cramping... I don't know if this is usual for me because I haven't been tracking everything for long but days 6 and 7dpo I had really strange cramps. Actually they weren't really cramps like AF type cramps but more like sharp stabbing pains, very very low down, almost at the pubic bone. They would last a few seconds at most and would come and go throughout the day. Some of them were really painful! Anyone else had these?!
