Am i crazy?

Okay so we are trying for #2 and i have 3 apps for tracking my period and fertile times all three have different suggestions about when i start and o. Also i have a 40 day cycle. Okay so based on the apps i was fertile from nov 28- dec 4. We did it every other day and im pretty sure based on cm that i o between dec 2-3 so that makes me currently around 8-9 dpo. I feel like im reading to much into things but my symptoms are these.... Spotting very light since sunday like twice a day, tired a lot getting 8-9 hrs sleep, dizzy spells, hungry a lot more than nornal really craving a hamburger and meaty stuff, slight cramping like i keep expecting af(not due til next weekend) and just recently tonight mt whole stomach is sore like i worked out when i def did not. I feel like it could be symptoms but i am just so afraid I am having smptoms just because im looking for them!!!! It is making me crazy obsessive!!! Thanks for letting be vent and share :)
