So anyway the last 4 days now I've had pretty bad diarrhea not even meds r helping tired nauseas on n off cramps n my stomach just kinda feels phone like a poking burning feeling it's not really painful but it also doesnt feel good also some pretty bad headaches .. I wanna be pregnant so bad but I also don't want to trick my body .. here'aprils n march charts
