Selective termination

I feel so low right now. I've been thinking about this all day. My husband and I have been trying to conceive for 2 years. I was put on femara with trigger my last cycle, and found out I was pregnant a little over 2 weeks ago. Well today I went into my ultrasound and they saw 5 heartbeats, my ovaries were overstimulated. My doctor is recommending selective termination of at least 2 of my babies because of my small frame and high risk. I have always been pro-life. I really don't know what to do. Advice, prayers and personal stories please. I didn't even know this could happen. I can't stop crying.
