hi nikki, sorry you are going through this hun
i have read and reread your first post and can't seem to shake the feeling that your doc is not talking about your fallopium tubes when he said "tube" but maybe means your cervix (kinda a tube, lol). when he said your cervix was tight in medical terms this is stenosis (for a word to google). cervical stenosis has been suggested as a cause of low fertility/infertility. the cervix is part of the uterus and is a muscle so it can spasm (like leasha said ).
so is it possible your fallopium tubes are not blocked, but your cervix spasmed?
sorry but have been tossing up if i should post this, hope i have made things any worse
i agree with the other girls re make another appointment, or get his findings in writting or both.
hope you get some answers
