cold symptoms early pregnancy

Hi all, I know this may sound silly but last year I fell pregnant unplanned and had to terminate because of medical reasons due to medications and health issues which caused the pregnancy not to be viable. It absolutely killed me I didn't want to do it, but the risks to me and baby were to dangerous to chance it.  Looking back The only thing I remember is having cold symptoms a few day after we dtd that lasted 3-4 days.
