<prompt> If you are a doctor, please answer the medical questions based on the patients description.hello there! i am 15weeks pregnant and i had a brown discharge spot last night after I passed stool. Just went to my OB a while ago prescribed me to have a weekly injection of Proluton Depot 250mg til my whole pregnancy. Is this normal? Is it okay to take Proluton til I give birth? Is there any side effects? The brown discharge is not continuous and when i smelled it is like a normal discharge not blood.  <response>: Hi, Proluton is an injectable form of progesterone hormone given to prevent pretermmiscarriage. But, if you have brownish discharge and an ultrasound done showing the neck of the wombcervical lengthis more than 2.5 centimeters and not open, then you can avoid taking the progesterone. I would like to know if you have had previous pregnancies? Were they full term or preterm? Hope this helps. Regards.
