My body temp has also been low, generally at least 97, sometimes below. While I've no reproductive system at all, I've never had what I've heard described as a hot flash. I get a little warm from time to time, but it is minor and passes quickly. More often I can't get warm! I do get a good thyroid workup at least once a year as it was removed 30 years ago. Generally speaking I'm colder than before my surgical menopause. I DO prefer to be outside, but I'm becoming less and less fond of winter...
