So last night I went to bathroom and has blood when I wiped. It stopped. I called the on call immediately and they asked about sex, strain, constipation, cuts or scrapes. None of that. So he said call in morning to come in and be examined. Has anyone else just had a burst of blood and never happen again? I'm 22 weeks pregnant. Just went for an ultrasound Thursday and everything was okay. Just wanted some input if this has happened to anyone else or what they think it may be.
