wazifa for children

Q: I'm 27 years old.  I had two abortions under some circumstances which were absolutely sin and I keep asking forgiveness from Allah for it. Now, I'm married and have one baby girl of 3 years old and we want to have another baby but it's not happening anymore. I am starting to get into depression as I'm scared that this is the punishment from Allah.

I have come to a conclusion that everybody has a number of kids allotted from Allah but since I have aborted two babies and I got one so now I may not have any baby in my life anymore, is this thought correct?  But honestly when I had this baby girl the only thing I thought is that may be Allah forgave me that's why he blessed us with his most precious gift - a girl. 

Is there any kaffarra for these sins and that Allah bless me with more kids?

Q: Can we do a wazifa for a boy baby? If yes, can you tell me about any wazifa for that?
