Since you are 3 months pregnant and have persistent stomach pain that has not improved with medicines, it is important to contact your obstetrician. Persistent abdominal pain in pregnancy can have several causes, some of which may need urgent attention. Do not take any more pain medicines on your own, and get evaluated as soon as possible to ensure both your safety and the baby's.

Pain in the uterine area that worsens after urination could be due to a urinary tract infection or another gynaecological issue. Anafortan is generally safe for relieving pain, but it won't treat infections. Norflox 400 mg is an antibiotic and should only be taken if a bacterial infection is confirmed by a doctor. It is best to consult your doctor first to identify the cause of the pain and get the correct treatment rather than starting antibiotics on your own.

Since your abdominal pain has not improved and your ultrasound is normal, it is important to follow up with your doctor. They may need to do further tests, check for issues or adjust your treatment. Avoid self-medicating until you get a proper diagnosis.

Since you have ulcerative colitis, it is important to be careful with pain medicines. Meftal is an NSAID and can sometimes worsen colitis symptoms or trigger a flare. Anafortan is an antispasmodic and is generally considered safer for menstrual cramps in people with ulcerative colitis. However, it is best to confirm with your doctor before taking any medicine, especially since you are on Mesalgine and Azoran.
