prenatal yoga?

Does anyone suggest this? I'm nearing the end of my first trimester and I want to stay active but it's so hot (I live in Texas) so walking my neighborhood during the day is difficult to do and I don't wanna walk in the evening bc of the mosquitos being so bad. I could probably do it early in the morning (walking) but still have the mosquito problem... I was just wondering if anyone suggests prenatal yoga and if you're doing it or have done it or even plan to do it 
TIA
