Hi.mim a 16 year old female. I've been on the contraceptive pill for 6 months and now 3rd day into my period. Yesterday morning I woke up and started to eat some porridge which I love and I felt I was going to vomit so ran to the toilet. Then 4th day into period now I have tight abdominal pains and aches which is spreading to right side of lower back , I've been frequently urinating and have a sharp pain when urinating in abdomen and bladder area. I'm also a lot more tired than usual. This is the second period these symptoms have occurred and it's onky when I'm on my period. I've had no sexual activity for 6 months. Is this an infection or bad period pains ? Should I see a doctor.? Thank you
