About ten days after the first day of my period i get a pain in my right groin. usually lasts about 12 to 24 hours can be quite severe at times (but not so bad that paracetamol dont help) and sometimes i feel just generally under the weather during this time. I am pretty confident that it is ovulation because it is a regular as clock work type pain..... i am just concerned as to why it is always on the same side.......... also have only had it since my periods returned after birth of first ds about 14 months ago.
