usually the temp rises a day or two after ovulation and then stays up till you are near AF..if the temps stay high upto 18 days after ovulation , it is one of the indicators of pregnancy..usually once the temps start dropping after ovulation, it means you should be getting AF soon...good luck!!
But will the dip last for like 5 or 6 days?
Although a random dip or spike is not uncommon, some people do get an implantation dip when they're pregnant...and with the cramps, too, maybe that's what it is! I sure hope so! Best of luck!
