In vitro pregnancy 10 weeks found vaginal discharge with blood may be related to preeclampsia, acute cervicitis, trichomoniasis vaginitis. 1. Pre-eclampsia: Abnormal embryonic development due to factors such as mother, embryo, father and environment. Vaginal bleeding may occur, but the amount of bleeding is usually small, mostly dark red or bloody leukorrhea. 2. Acute cervicitis: often due to pathogen infection, physical factors, chemical stimulation and other causes of cervical injury, the cervix appears to be infected, resulting in cervical congestion, redness and swelling, there may be bloody discharge. 3. Trichomonas vaginitis: often due to Trichomonas vaginalis infection, resulting in inflammation of the vagina. Inflammation causes bleeding spots in the vaginal mucosa, which ruptures capillaries and causes blood in the leukorrhea or bloody discharge. In conclusion, if you find blood in vaginal discharge at 10 weeks of IVF pregnancy, it is recommended that you consult a doctor in time, follow the doctor’s instructions for further examination, and choose a reasonable treatment plan under the doctor’s comprehensive analysis.
