My wife had a hystorectomy 7 weeks ago. We Just had sex for the first time since the surgery and afterwards she had bleeding and server pain. She says the pain is felt more in her back. Is this normal, is it just scare tissue and this will all go away? She was given the OK from her doctor to resume everyday activities. She didn't ask about sex but she did ask about working out at the gym and was told that she could do any workout she wanted to so we assumed sex was OK. Should she be concerned
