Hi Geo, I could have written a lot of this post 28 weeks ago!
I found out I was pregnant and was completely shocked and terrified - I was not remotely excited and all I could think about what how I would lose my independence, had already lost a massive chunk of my identity, didn't know whether I had made a huge mistake getting pregnant in the first place, was confused about my social life now I could no longer drink etc, felt awful with morning sickness which never helps anything, was worried that my baby wouldn't love me or that I wouldn't love him - it was awful.
I sobbed and sobbed at my booking in appointment and it really was terrible - I felt pathetic and really, really depressed and frightened. The midwife asked me outright whether or not I wanted my baby and that was probably the first time I realised that as terrifying as the whole thing is and regardless of the state I was in, I wanted him more than anything and had done since the second the second blue line appeared and I realised he was coming along.
I spent a long time feeling guilty that I wasn't shout-from-the-rooftops happy and enjoying pregnancy when so many other women struggle to get PG and would love to be in my position but then my midwife told me that it their experience isn't my fault and I am entitled to my own feelings - that really resonated with me and I tried to be less hard on myself about the whole thing.
It hasn't been plain sailing, I have had some antenatal depression and have needed some mental health support through my pregnancy (I did have pre-existing MH issues though) as well as needing to speak in detail with the birth talk midwife at my hospital - I was initially terrified of giving birth and wanted an ELCS initially.
As well as the shock of the pregnancy I also had bad morning sickness and a stock of other symptoms which made the depression worse I think. Luckily, at 15 weeks the sickness stopped and then a few weeks later I started to feel my baby moving and if I wasn't in love with him before (I was) I was completely besotted when I felt those first little wriggles. Not in a cheesy Earth Mother way though, I feel more like he is so much a part of me and we have been through so much together.
I am currently nearly 34 weeks PG though and I AM SO EXCITED! I can't wait to meet my little man and see his little face and touch his soft skin and look into his eyes - I can't believe how much has changed since the early days and the booking in appointment meltdown.
Give yourself some time to let the idea sink in, keep talking to DP and to people on Mumsnet and your friends in RL if and when you can. You wouldn't be human if you weren't absolutely terrified!
