pregnancy at home exercises to lose excess fat?

Diary of a Fit Mommy website and her Facebook both have a lot of nutrition info and workout videos that are great.

No. Just, no. Of course it's fine to exercise when pregnant but doctors will usually advise you to keep to the same level of whatever you've been doing (ie: not more strenuous). Furthermore, there are no exercises that, by themselves, will help you lose fat; it comes to burning more calories than you take in. I don't know if that's something you want to attempt to mess with right now, since doing it wrong could deprive your child of nutrients... The best thing you can do is eat healthier. As to exercise, I'd say yoga (within reason), or talking walks when the weather is okay. All of what I just said is moot though, if you are like I was, at the end of my second, gaining 20 pounds of water weight from toxemia. IMO, just make good food choices and when the baby comes, if you nurse , trust me, the pounds melt off as long as you aren't overeating.

You are going to control the weight gain by limiting what you eat. If you are gaining faster than ideal, which sounds like the case, then you are eating too much. Even if it is too much of good things. If you have already changed this, and know you are not overeating (regardless of quality of food), then things will gradually even out.
It is not a good idea to start a new exercise routine during pregnancy, unless it is something easy on your body, and ideally with some coaching. You can walk, and this something usually many drs recommend (at a comfortable pace, and gradually increasing distance, do not try walking for 2 hours if you have never been into walking before), swimming or a water-based class, try yoga.

I think the first thing you ought to do is change your attitude about what you've already gained. Ten pounds in the first trimester is really not that far off from the recommended amount (four to six). I completely understand wanting to limit fat gain during pregnancy, you must understand that your body does need to store some (they say five to ten pounds) fat during pregnancy.

That said, the one thing did to prevent extra weight gain was to use my ellictical evey day for an hour! I did not go from doing nothing to an hour in one day, though. There is nothing magical about the machine. If you walk briskly for an hour every day, I think you will find you have a much easier pregnancy, labor, and recovery. Congratulations!
