Hello doctor,

I am 17 weeks pregnant. In my USG report a blood collection is found of 52 mm x 20 mm at internal os. I am very worried. What is to be done with the problem?

Welcome to icliniq.com.

How are you doing? After 12 weeks pregnancy, the risk of bleeding is low. Only a bleed from the margins of placenta is to be worried about. Cause of this collection could be:

1. Erosion and thereby minimal bleed from the raw surface of erosion. There may be mild discharge with or without some altered blood. You can have vaginal antifungal or antibiotics like Cansoft CL or Candid V or Clingen Forte once at night for 5 to 7 days.

2. If you have had sex recently. Above medications can be used.

3. I hope cervical length is greater than 2.5 cm and internal OS is closed. If not, you may need a cervical cerclage stitch.

To be on a safer side, you can have:

A. Injection Proluton depot 500 mg IM once in two weeks for 1 to 2 months.

B. Capsule Susten or Dubagest or Naturogest or Vagestone 200 mg twice daily vaginally for 1 to 2 months.

These both can be used simultaneously. They both are Progestrone hormone. They relax the uterus and if the blood has any chance to irritate the uterus, these two will stop it. So can prevent preterm labor pains. It is not easy to prevent pain once it starts, so better to use it before any risk factors. I do not think there is anything to worry, avoid any strenuous work, journey and sex.
