every month my cycle is 30 days on the dot. last month i was on cycle day 40 before i got my period making me 10 days late. i always get cramps about 3 days before my period which i got 3 days before my projected start date and then nothing. me and hubby thought we were pregnant so i went to get a blood test was negative and next day i got my period. this month again i am on cycle day 42 (12 days late) no sign of starting anytime soon. we don't wanna get our hopes up like last month bc we were destroyed but don't know what the deal is. when should we test this month?
