I've been giving myself the shot in the belly but I'm afraid when I'm further along this may become harder to do. My Dr. says she has some patients that give themselves lovenox shots in the thigh. That sounds painful!
Ditto the love handle area. I am an ER nurse and this is where Lovenox is supposed to go. However, I do not think that all teaching is accurate- several times I have given patients the injection, then they say "well when I have given it to myself before I do it near my belly button." I don't know who is teaching self-administration to these people but it isn't following the manufacturer's guidelines. Part of why this is probably so common is that a "normal" IM injection of insulin or some other drug generally does go closer to the belly button.
There are illustrated pictures here. I think even at 35 weeks, as stretched as I am, I have enough subcutaneous fat in my love handle area that I could still administer it there.
Also, remember to rotate to different sites between each injection if possible- as you probably know, you can get big bruises if you don't.
