hello and welcome,
The most likely reason for this seems to be a condition called endometriosis
. In this menstrual tissue grows inside the uterus
and sheds there during periods leading to pain. It cannot be seen on ultrasound
unless it produces ovarian cysts [ chocolate cysts] or tubal pathologies. Can be detected by a doctor on vaginal examination and also by laparoscopy
Other reasons are pelvic congestion where there is increased blood flow to the pelvis. Usually relieved after periods.
Pelvic infections may also produce pain.
The endometrium is thick if there is increased estrogen
. So it depends which day of the cycle the scan was done. If done on day 13-14 this is just slightly more 1-2mm more than expected.
Al in all the best empirical treatment for you now is either low dose oral contraceptive pills
like ginette or progesterone [ medroxyprogesterone
twice daily] from day 15 to 21 of every cycle. A cervical swab test may be undertaken if infection is suspected and then antibiotics will help.
Discuss these options with your doctor and then start treatment.
Hope this was helpful.
Feel free to ask any further queries and I will be happy to help.
Thanks for using HCM.
Have a good day.
