Good day. Could anyone have had a similar case? Please advise on how to proceed. Pregnancy is 5-6 weeks. Gynecologist hasn't put it on record yet (I visited her two weeks ago, as the blood test arrived). The last visit to the doctor was November 3rd. I complained about cystitis and back pain. The doctor prescribed a urine analysis referral. Nothing was prescribed until the results were received. On November 10th, I went for an appointment. For the past three days, there have been dark colored discharge. Back pain has intensified today. There is a lot of discharge. How should I proceed in this situation and where should I go? First pregnancy.
