HT, I am SO sorry. I was faced with a similar situation a couple of years ago. The day I found out I was pg was the day I heard my specialist say, "maybe cancer." My husband was gone for a few months on work and could absolutely not talk about it on the phone with me (he was leading a mission trip and Abortion was not something he could talk about on a public phone.) I had two small children and the diagnosis would not be in for a few weeks, still a lot more testing to do.
I had one week to decide if I wanted a medical abortion (via pill) or wait and face a surgical abortion (you know, the pics the pro-life folks show you). I could not stand to do a surgical abortion but I did not know for sure that I had cancer, either. I just couldn't wait for the tests to decide. I had to make the decision alone b/c my husband could not be reached by phone.
I chose to stay alive for the children I already have. My worst fear is leaving my babies without a mother. I could NOT NOT NOT. I couldn't. So I asked my mother what she thought about abortion and she said, "It's a sin. Period." Then I told her I was going to have one. She held my hand and sat by my side for 24 hours straight. She loves me in ways only a mother can.
I hated myself for about a year and a half and it was an issue in our marriage. My husband knew what had happened, but he wasn't there with me. He did not hold my hand. he did not understand how broken I was.
I am lucky to belong to a church community that welcomes me without judgement. It took a long time to really understand that God forgave me and the real work I had to do was forgive myself. But all along, I knew I made the best choice I could with the information I was given; and no, it turns out I did not have cancer. I had been very sick for months and to this day we don't know why.
I am sorry for what you are going through, and I hope my story shows you that you are not alone. Women face really tough choices. Do not let anyone stand in judgement of you -- honestly that has been the hardest thing. I feel like I SHOULD hate myself more because so many loud people hate what I did. But in the same situation I guarantee you that a good number would do what I did and just not talk about it.
I was going to PM you about this, because I am hurt by the pro-life folks who have never been in this situation, but I guess that is exactly why I feel the need to post it openly. Who among them would have raised my children for me?
I hope with all my heart that you are healthy and I wish you peace with whatever you decide.
