Hiya, I'm in a bit of a different situation to you as I am 23, but my pregnancy was very much unplanned (I'm now 29 weeks). At first I went into a complete state of shock and panic. I couldn't see there was any way that I could be a good mum and it seemed like the worst timing financially etc. I felt no connection to my baby and felt like I would be the same cold detached mother as my own.
I thought I might have to have a termination because I convinced myself I could never love my baby. However, I gave myself some time. I stopped judging every negative thought and allowed myself to feel whatever came up. I gave myself until 12 weeks to make my decision. Slowly over those weeks I calmed down and started to entertain the possibility that my assumption of the worst case scenario was not necessarily true.
I started to see there was the possibility that I wouldn't be like my mum, that I would love my baby and that i had the potential to be a good mum. I decided to keep my baby.
Over the last 7 months that little spark of possibility has grown into confidence and excitement. I have gone from feeling no connection with my baby and struggling to share my body, to a strong bond and loving feeling towards my little girl.
I have 11 weeks until my due date and I now can't wait to meet my baby girl. This pregnancy was not at all planned, and I was sent into the depths of dispair at first, but over time that has completely changed and I now couldn't be happier.
I'm going to be nothing like my mum, and neither will you. Good luck op, give yourself some time to get your head around things. Don't be hard on yourself, anything you are feeling is 100% ok.
