Hi! I had miscarriage at 9 weeks pregnant when baby stopped growing at approximately 6th week . I took misoprostol this past Saturday . Went to my gyn doctor who said that based on sonogram exam I have passed everything and should be fine now . One and a half day after started to have ins tense pressure when urinating and pain as well . In addition , I am experiencing intense lower back pain and some abdominal pain under the pelvic bone area. I am 40 years old , 125 lbs , 5'4 , first time pregnant , no bad health history . What could it be ? Please let me know .
