I am 29 weeks pregnant. I had a stitch put on my uterus in November as internal os was open and cervix length was short. But on Sunday I had bleeding (spotting) of 4-5 drops. I was very worried so I showed the doctor. She asked me to take bed rest but didn't tell the reason behind the spotting. Please advise what would be the reason and is it safe for me? I am very worried.
