I might be pregnant if I am should I tell the ex.?

to me it sounds like you worrying to soon. firstly find out if you are pregnant. secondly you need to let go of all the negative s**t. you were together for a year and half so there must have been love there at one stage. if you are pregnant yes i would tell him as he has every right to no but don't expect anything from him then you won't be disappointed . your lucky you have a good family and Friends around you,. so concentrate on that. and if your pregnant them work from there. best of luck
