Pregnant after Plan B

I’m a married mom of 3 and I just found out I’m pregnant again. We had a slip up and I took a Plan B pill within the hour of sex but it was during my ovulation week so it obviously didn’t work. I have never had an abortion before and it was never something I thought I would consider but I’ve got some medical issues I’m dealing with currently and I just don’t think I can have a baby right now.

I haven’t even missed my period. I tested with an early response test. It looks like my best option is the pill.

I’m just looking for reassurance and or feedback. I don’t feel like I’ll regret it but I am a little scared of the whole process.
