Stressed out\alone

Hello my name is Bri I am 30 yrs old and I have been TTC for a year now and my fiance who is 37 has a 2 yr old son from a previous relationship. I have had a miscarriage back in 2016 I was only a week along . I have always wanted kids of my own and my fiance and I would like to start a family together I have been to the obgyn and the doctor there had put me on pretablets but I stop taking them. I have a regular period every month right now I am 4 days late but I don't want to take a test yet cuz I don't want to be disappointed again. I don't have no friends to talk to can't talk to family and my fiance says I don't my no sense when I talk to him bout anything I'm really in need of a friend to talk to and to listen and give me some good input.
