You know the implications of having an abortion having gone through two in the past. I am not against abortion, but personally wouldn't have an abortion again myself, as one year later I am suffering a fair bit of grief, and having phantom pregnancy symptoms, at least this is how I feel. Tests are all negative though. However if I did ever get pregnant, I would keep the baby no questions, no matter what situation.
I think that you are very strong as a person to go through so much, and don't feel humiliated, it's not something to be humiliated about. It's just something that you have to live with.
I feel that you should take time to look inside yourself, mediate, or go to a few meditation classes and truly look into yourself to see what you want, not what anyone else wants. If you look inwards you will know the answer, whether it's time or not, just don't doubt yourself okay!
You know what's best for you and how this will effect you, noone else.
Good luck honey, take care x
