if your symptoms are related to peri-menopause they will not completely go away on their own (at least in part). I would expect your cramping to go away on its own - if it continues you should at least take a pregnancy test to make sure it isn't something serious like a tubal pregnancy (although unlikely). If it seems to get worse an ovarian torsion would need to be excluded.
If the pain and dryness is related to perimenopause you may see good days and bad days as your hormones fluctuate. This will not go away on its own, but can be easily treated by vaginal estrogen - you would need to see your doctor for this so he can make sure you are perimenopausal. This would be important because you are quite young to be perimenopausal, and it is a myth that only menopausal women have hot flashes - all women of all ages can have hot flashes.
lastly, try a lubricant and increase stimulation before intercourse - these things might help.
