7 months ago, I had a history of fetal loss. After that, my menstrual cycle returned to normal. My cycle is 30 days, and it ends after 4 days. On December 18, I had a period, and then on January 17, my period was due but was late until January 25. I used a pregnancy test strip and saw one faint line and one unclear line. I went for an ultrasound, and no gestational sac was seen. On February 1, I had another ultrasound, and the doctor said there was a gestational sac, but it was still unclear, so I should keep monitoring. The doctor calculated my pregnancy at 6 weeks, but the gestational sac is still unclear, and I am discharging a little bit of black blood. I told the doctor performing the ultrasound about it, but the doctor did not say anything. Doctor, may I ask if black bleeding at 6 weeks pregnant with an unclear gestational sac is harmful or not? What is the reason for this black bleeding? Thank you.

Last month, I was pregnant but had a miscarriage at 7 weeks and underwent a termination of pregnancy (TOP). During that time, my husband and I had sexual intercourse. Currently, it has been a little over a month, and I have been maintaining a healthy diet and taking traditional herbal medicine daily. Suddenly, today I started experiencing persistent lower abdominal pain, which worsens upon standing and improves when lying down. I would like to ask if it is normal to have persistent lower abdominal pain one month after an abortion. Thank you.
