Pregnant with out a kidney

Jasmine
I'm pregnant with my second child I am 18 wks pregnant. I donated a kidney to my sister about last Christmas but I have a lot of question regardless I don't have one kidney because I donated to my sister I have always been really healthy but right after I gave her my kidney I lost a lot of weight and I just gained it all back up I don't know exactly how but I would lik to know if there anyone out there that donated any organs n that can relate. My doctor said everything looks fine n that there's no need for a C-section which I'm really terrified off .well if any of you guys are or could relate to my question or story just let me know
