enough gas to fuel a busline!

so I'm 10dpo did a test yesterday was a BFN. HAVE been soooo gassy it's embarrassing! some cramping but not sure if it's AF gearing up or gas cramps!?! keep hoping it's implantation though. headaches for 4 days straight. boobs are tender but no more than normal. stuffy nose but it is that time of the year. The one thing that's got me thinking maybe is went out to eat in Sunday I was starving but when the food came instant loss of appetite only ate a couple bites of soup very strange for me as I am a major foodie! trying to wait and test on Saturday. sure I won't be able to hold it though.
