Oh Carrie!
I hope everything is ok!
I have heard of a lot of women who bleed in early pregnany and go on to have successful pregnancies. Is it possible the suppositories were aggravating your cervix and causing you to bleed? I know that happened to me on Crinone. Also, I have heard that different labs have different numbers so I wouldn't bank on that value you got at the hospital. I know my clinic makes you pick a place to get blood drawn and then to stick with it b/c of the different values.
You are in my thoughts. I hope that the bleeding was nothing. Keep us posted.
