Why Do I Have Excessive White Discharge and Abdominal Pain with Missed Periods?

See a gynecologist for an examination and diagnosis. Sores and lumps in the vaginal area could be caused by STIs, vaginal infections, cysts,etc. Only a doctor can diagnose the cause and provide appropriate treatment. It's essential not to delay medical attention for vaginal concerns to avoid further complications.

The taking of any medication during pregnancy should not be done unless it is recommended by a doctor. Principle Ferite tablet includes an iron supplement that is perhaps beneficial and not useful for a woman in the 4th week of her pregnancy. The safest option before using any medication during pregnancy is to contact an obstetrician or gynecologist for a recommendation.

If you miss a period for more than 3 days, it may be implantation bleeding as well as a medical condition. A gynecologist should be consulted for a thorough examination and diagnosis. The gynecologist or an obstetrician is the best consultant on such conditions.
 

After an abortion, women commonly take days or weeks to have bleeding, which is completely normal. Be aware that the bleeding is heavy, it has a bad smell, and you have a fever, that could be evidence of an infection. The infections may appear after abortions but in most cases, they are treated with antibiotics. 

This symptom could be an indication of a vaginal prolapse or some other medical condition. Consulting a gynecologist who can diagnose and treat the condition properly is of importance. I suggest you to see a gynecologist for an examination immediately.
