Hey OP, first of all, I just want to say that you are not alone in feeling this way. I think we’re probably in the minority, but trust me, not every woman loves being pregnant. I felt so many of the same things you’re describing, and more.
I searched these boards and other communities looking for someone who felt the same way, and I found so little out there. Perhaps it’s still a bit taboo to admit that pregnancy can be a really miserable experience, and that can make you feel incredibly alone. I remember feeling so baffled when people would say how much they loved being pregnant or how they’d breezed through all nine months. I genuinely couldn’t relate.
However, I will say this: hindsight is a funny thing. Once the sickness subsided, I really wish I’d been sooo much kinder to myself. I wish I’d taken more bump pictures, even with the stretch marks and despite feeling so wretched. So, with the little time you have left, might I gently suggest taking a few photos of yourself, for yourself? Perhaps with a bedsheet as a backdrop and your favourite dress, or something you feel nice in. I wish I’d done more of that.
I too felt so exposed during pregnancy. Having to get on the Tube and go to work while feeling utterly self-conscious about my changing body was really difficult. I also put on a lot of weight and had quite a bit of water retention, which only added to how uncomfortable I felt. One small consolation is that I think most people look at pregnant women with a sense of wonder, even when we feel anything but wonderful ourselves.
If you can, I’d also encourage you to spend these last few weeks resting, relaxing and perhaps connecting with your baby in whatever way feels right for you. I wish I’d had more time to research breastfeeding, too, because the education and support I received in hospital were woefully inadequate, and I felt quite unprepared.
And please remember that you will feel like yourself again but it might take time. Forget the whole “nine months in, nine months out” thing if it doesn’t fit your experience. People will give you all sorts of timelines, but your body and your recovery are your own. Give yourself permission to take as long as you need.
For me, though, one of the most incredible things was looking into my baby’s eyes for the first time. It was pure magic. There was this overwhelming feeling of knowing them forever, even though we’d only just met. Nothing could have prepared me for it.
I really hope you get to experience that feeling, too. And I say this not to dismiss how hard pregnancy is or to suggest that the end automatically makes all the difficult bits disappear, but simply because it was something so unexpectedly wonderful for me.
Above all, please be nice to yourself. You don’t have to love pregnancy to be a great mum, and struggling with it doesn’t mean you love your baby any less. You’re allowed to find this hard. And remember, you never have to do this again if you don’t want to.
