Third trimester and eating junk

Im 35 week now and have been eating quite healthily up till my third trimester but ever since I've entered my 3rd trimester, I just feel like eating junk all the time. Fried food, ice cream, snacks, bbt, macdonalds... all these food like at least once or twice a week. Sometimes I can eat ice cream 3times a week. I feel so bad to my baby, but I can't help it. I try to compensate and eat more fruits and veg in my other meal. Is anyone else like that? :( I really hope I'm not the only mama here who can not control her cravings. Will it affect baby?
