miscariage

i had a miscarriage thursday night i told my boyfriend and showed him the utra pic on saturday night he hasnt really spoke to me since im at a lost i know it was going to be his first baby ... i lost my baby 16 week preg i was on the iud and i got it taken out they said the baby had 50% chance of making it or not .... but i know we handle our emotions differently but i will just give him space ...i been very sad myself i been doing things to keep my mind off being i have be strong for other 2 kids from a previous relationship .....and i also been thinking when is it the time to have sex after a miscarriage and when is it the right to try for a baby after a miscarriage
