How many calories are you ladies eating in the third trimester? I'm moderately active, I'd say at least 3 times a week I do cardio and light weight lifting. I aim for 5 but I get tired lol. I was gaining a lot of weight so I tried to slow it down and cut back my calories, but now I'm worried I'm eating too little and I don't want to hurt my baby boy. I just got freaked out. I'm trying not to take in more than 1600 a day, is that too much?
