Patient's question:
The period arrived on the fourth of last month, and around the fourth of this month, it started to be a bit like it was going to come but didn't. It has been like this until now, without any abdominal pain or other symptoms.Doctor's answer:
Posterior fornix puncture is performed because blood tends to accumulate most easily in the rectouterine pouch of the peritoneum. Even if the blood volume is small, it can be aspirated through posterior fornix puncture. Using an 18-gauge long needle, insert it from the posterior fornix of the vagina into the rectouterine pouch. If dark red, unclotted blood is extracted, it indicates a positive result, suggesting the presence of intra-abdominal blood accumulation.
