Seriously in shock

Seriously in shock. Been ttc for almost a year. This month only bd 1x during fertile window while on vacation. Didn't do any tracking other than calendar. Only thing different this month was I started going to the chiropractor. I have had way more "symptoms" previous months when I got BFNs than I do right now! Boobs barely tender, gas and indigestion, had one day of sharp lower back pain. Really hope it sticks!!
