My last period start date was June 18th so would be about 3 weeks if go by that. My stomach is getting bigger I am gaining weight was 94.0 in beginning but am now 97.6 I am always hungry and usually I don't eat that much but it's like I can't beat my hunger I am peeing just a little more than normal have felt like gonna get sick only twice. Having like tight stretch feeling in stomach and lower area, very tired this would be my third pregnancy and I feel as if I am but do not want to just go by my feelings what do you all think.
