It's to soon. Never thought I'd be in this position.

So Friday I found out I was pregnant. I have a 5 month old baby. I was on the IUD and the ONE time my husband didnt use a condom since he dosent believe in birth control, I end up pregnant. We can't do it financially and I cant do it for health reasons. I'm 6 weeks pregnant. Doctor offered me the pill method since he know our situation very well. But I still cant help but feel sad and heart broken. I know we HAVE to do down this road. It just really hurts. I can't tell my family because they are VERY against abortion no matter the situation and they wouldn't understand. I've always been pro life, and its crazy how in a blink of an eye things change. Asking for prayers and support please. Any of you taken the abortion pill before ? How does it work.
