These are all questions for your practitioner, but, yes, if you were told you were blood deficient, as my answer already indicated, tonify the blood in Chinese Medicine terms would be appropriate. As to whether or not that will help your memory - in technical terms it should. But not knowing your medical history or other issues you have (and knowing there are many, many ways to have memory issues) these are questions only your practitioner can answer armed with more personal information than is appropriate for an online forum.
With regards to natural birth and c-section. I think your word of “damage” would be incorrect for either. Obviously with a natural child birth things follow their own progression allowing the body more time to adjust hormonally, physically, etc. A c-section is traumatic to the body, but compared to a non-productive labor that goes on for days or other complicating factors it would probably break even in some ways affects wise from a TCM perspective. It’s all relative.
What’s more important is the health you have before you go into pregnancy, the health you foster during pregnancy and the things you do to smoothly facilitate labor and these are all aspects that consistent acupuncture treatments can provide before, during, and immediately after pregnancy.
