After I found out I was pregnant I announced it about 2 weeks after I found out when I was 3weeks by blood test anyway ever since that my "friends" completely disappeared seriously no one talks to me anymore I'm not sure why I never partied I never did drugs or anything so I don't get why they are being like this .. my sister is planning my babyshower and she told me to get my friends names and addresses and I literary only had three people and its making me depressed I feel very alone .
