Girls, hi! I have such a question, do you engage in any kind of sport or at least stretching during your pregnancy? I started doing yoga years ago because I had back problems. For three months I haven't done anything, all kinds of loads were banned before the embryo transfer. And as expected, began to painfully hurt my back. Wait for a doctor's appointment and ask if it's possible to do something light, what do you think?
