Thinking about having an abortion...

I am about 5 weeks pregnant and in no way ready for another since I have a 15 month old. I feel so bad because with my first baby from the first minute I knew I was pregnant I felt so attached and connected & with this pregnancy I feel nothing at all. I watched a video about how a baby is formed (I did it with my first) and this time I just felt nothing.. I just feel so bad that I’m even thinking about having an abortion. Can anyone please give me advice as in which type of abortion they had? & the difference between all of them?

Sorry about my post being all over the place.. I’m just so confused and don’t know what to do.
