user1492515675 I've regretted (and still do regret) ever suggesting to my partner we try for a child - everything was 'perfect' in regards to our life / financial situation (and thankfully, still is) and so it just felt like it was a natural next step to do - I 'planned' everything - took folic acid, ate healthy, was already charting my periods... however it was a massive shock when I found out I was pregnant and hysterically sobbed down the phone at my partner, apologising for ruining his life and saying 'I totally understand if you want to leave me' 
I don't regret terminating - I don't think it was a choice per se, as I truly believe if I had continued with the pregnancy, I would have taken my own life. I guess that's something I'll never know - However even with anti-depressants, I felt I just couldn't cope with being pregnant.
It's worth noting, I've got massive, massive phobias about injections / medical professionals and hospitals in general, based on an event that happened when I was 4 years old. Additionally, I was one of my sisters birth partners (along with her Husband) 3.5 years ago and it was a very traumatic birth - which I witnessed in full. Part of why I felt I couldn't cope, was to do with the fact I thought I'd have the same birth and not be 'in control'. I have had (and still have) counselling weekly and that's helped significantly - especially considering every single Doctor / Nurse / Midwife has been nothing but sympathetic and supportive which has challenged my negative opinion completely and has turned it around.
I'm 35 now and appreciate that my chance to have a child is decreasing - At the moment, I'm in the 'no' camp.... even if someone said to me 'You have 3 months to get pregnant or that's it, you won't ever have children', I wouldn't do it - firstly, because I don't 'feel' any desire to have them, and secondly, because I don't want to run the risk of feeling so bad again and having the same outcome.
I'm 100% pro choice and whilst some women can terminate and feel emotionally fine - I was really taken aback by how I felt afterwards... guilt / regret over the situation / the 'what if's'..... Physically, I healed really quickly, but emotionally, it was a lot tougher.
