Hey Coral,
If your mother experienced having three children young then she is bound to come around to you having a child young.
Parents often aren't expecting to hear that their children are having children, they probably still see you as their baby so to find out you're pregnant or for any parent to find out their young daughter is pregnant is shocking.
Is going through with having this baby something you really want to do?
You really have to weigh up your options and make the best decision for you and no one else. Of course people can tell you what they think is right but ultimately it's you who is going to have to live with the consequences of the decisions you and your boyfriend make right now. Are you ready for a child or do you think you would be unable to cope?
Parents usually take some time to get their heads round to these things. I'm sure you'll end up figuring out what you want and eventually your boyfriend will be absolutely fine with you once he manages to get his head around things.
Best of luck to you.
PM me anytime, Paige
