Please tell your mom. She loves you, and would not want you to be in pain. Ask her to please take you to a doctor, so you can be treated for this. God Bless - Blu
Yes I would talk to your doctor about the possibility of Endometriosis.
Please look into that and check the symptoms to see if you have any other ones. This is not something you want to leave.
If you feel that its a possibility I would make an appointment with your GP and bring it up.
You should talk to your mum and ask her to take you to the doctor so that she/he can find out what is going on.
You may have a fungal infection, or even a urinary infection like Cystitis. These can cause stabbing sensations in that area.
When you have finished your period, take a urine sample to be checked.
The doctor will need to identify what is causing this problem so that he can treat you appropriately with the correct medications.
Make sure you keep clean. Do not use harsh soaps and bubble baths down below and wear cotton underwear. Also do not wear tight clothing.
When you use the toilet to empty your bowels, wipe from front to back. Because women have short urethras (where your wee comes from), bacteria can enter it and cause problems.
Have you been on any antibiotics recently?
Make sure you eat a healthy and balanced diet and drink lots of water so you do not become dehydrated.
We all get problems, no matter how old we are. So talk to your mum and let your know so she can take you to see your doctor.
Let us know how you get on.
Best wishes.
