Ttc 11dpo symptoms PLEASE HELP

[Loopylou7]

Hello please someone help me I'm SO confused. DP and I have been ttc #1 for 5 months with no luck so far :( currently 11dpo

So every month so far I've always got sore boobs about 1 week before AF due which always stops about 12 hours before it actually starts.

BUT this month I got sore boobs 2dpo which has NEVER happened before so I was quite hopeful. However today I woke up and my sore boobs were gone! Its now 18:45 (aka 12 hours later) and no AF. To confuse me more earlier today I got quite painful cramps in my right side and lower back which lasted 2 hours and while they were happening I felt VERY nauseated and was burping a lot. These cramps are not my normal cramps i get before AF. I caved and took a test but BFN :( but it's still quite early as I'm not due on for another 3 days!

My questions are:

1. Did anyone have sore boobs which disappeared one day and then go on to have a BFP??
2. Also could the pains that I experienced today be implantation pain this late in the cycle?

Are these symptoms or am I just clutching at straws? Please help!!!

Hi
I'm 11dpo today. Started to get faint lines yesterday. I didn't get sore boobs at all. At about 7dpo I got a stabbing pain in my left one and it went away very suddenly. I have been cramping since around 8dpo and these feel EXACTLY like af pains for me.

Hope this helps. Good luck!
