Miscarriage..

So I’ve had my first pregnancy at 20 but unfortunately I had a miscarriage. I didn’t know I was pregnant and I was spotting for about 3 weeks around when my period would have came. Mind you I didn’t have my period for 2 months but that is pretty normal cause it comes and it goes. Anyway. I really didn’t take it that hard because like i said I didn’t know I was pregnant but i think what hurt the most was that me and my boyfriend have been trying to have a baby for a while now. I don’t really think it has really hit me yet. When ever someone mentions a baby i just start crying and feel some type of way.. I think that is was hurts the most... any advice on what to do after a miscarriage or tips ?
