I aborted a six to seven weeks pregnancy seven months ago. I have been having normal menstrual periods for seven months. This month my period was normal,but my stomach was bloated and had shortness of breath too. I was put on ciprofloxacin and tinidazole tablets while menstruating. After one week, I experienced movements in my stomach in form of beats then the following day I started to menstruate and its been two days now. The bleeding is not heavy. My question is: what could be causing this and is my condition life threatening?
