Spotting at 25 weeks pregnant
Hello. I am 25 weeks pregnant. On Friday night after straining during during a bowel movement, I had some slight vaginal bleeding/spotting. I went into the emergency room and they did vaginal examination (where they saw some minor bleeding), an ultrasound (that turned out normal) and other blood tests etc. the bleeding stopped that night and was only light bleeding but they kept me in hospital for 3 nights for monitoring.
The doctor diagnosed me with a minor placental abruption even though this did not show up on the ultrasound (apparently ultrasounds only pick up about 50 percent of abruptions). My question is this: could the bleeding have been caused from straining too hard on the toilet? I am terrified about this placental abruption because everything I read on it says how rare and serious it is. The doctor came to this diagnosis through a process of elimination but I am wondering whether the spotting was caused simply from straining too hard on the toilet as this is when the bleeding occurred and it stopped almost immediately.
