The reaction I'll get when I tell people will be negative..

Laura
Hi girls ... I'm really struggling and need some help, I found out I was pregnant on New Year's eve , I was so happy but so sad at the same time I am 20 and my boyfriend had the same reaction.... We did want a child and we both took the step to not try for a baby but also not try to avoid it.. It took 6months ...
Now my boyfriend had done a lot of things early on in our relationship... Cheat and talk to girls my whole family hate him but I stuck with him which was my decision ....
Now I'm struggling to decide what to do on one hand I'm over the moon I'm pregnant but when I announce it to my mum and everyone else they will be so angry and disappointed.. And what if my boyfriend cheats again I'll be alone.. 
I feel like I should 100% take responsibility for what I have done and keep the baby as I decided o stop birth control 
It's just all so real now 
And I'm terrified of everyone's negative response 
I wanted and visioned when I became pregnant people jumping for joy but this is not going to happen...
