Hi LP,
I'm sorry you're feeling scared today. Are you still ttc? My experience is different because I started ttc and became pregnant in 2011 fully believe it would be the best thing ever. Almost immediately after become pregnant, despite not having any unpleasant symptoms or sickness and a straightforward pregnancy, I hated it. Absolutely hated being pregnant, I felt I had a parasite, my body wasn't my own, I couldn't wait to have the baby out of me. This reaction shocked me so much because I had wanted to be pregnant for so long. However, despite feeling like thins, I did manage to get through the pregnancy and now have a beautiful dd and am actually pregnant again, so it didn't put me off. I still don't like the feeling of being pregnant but at least this time I got pregnant expecting to hate it so I wasn't shocked at my feelings.
My coping mechanism were to focus on none pregnancy related aspects of becoming a parent, almost as though I wasn't pregnant at all and I was just preparing for tha spontaneous arrival of my baby. I should say, that was just something that worked for me and it wasn't recommended by a health specialist and I suppose could actually be a form of denial but it worked for me. I would think of how it would be after the pregnancy rather than the pregnacy if that makes sense.
Also, actually being pregnant fostered a sense of responsibility for this baby in me, even though I didn't like having the baby inside of me I was conscious that it was my responsibility to keep baby safe until she was ready to come out. Somehow, these two thoughts were seperate in my mind so I could just focus on keeping baby safe without associating with my own personal emotional discomfort.
Most importantly, and this is more true of this second pregnancy, I never felt guilty for feeling this way because it doesn't mean I don't want or love my baby it just means I don't like being pregnant.
I know my experience is very different because I didn't had a phobia of pregnacy just a immense psychological dislike of being pregnant so it's not quite the same. Deciding to become pregnant a second time was hard and I was very scared of doing it again but at the same time I was prepared for how I would feel.
I hope that helps a little. I think the important thing to remember is once you are pregnant if you can seperate your feeling towards your baby from your feeling towards/about your body it may make it easier to cope with it. Also don't feel guilty about feeling this way.
