I have never been over weight. Always healthy and moderately active. I’m 5’6” and my average weight is 140 - 150. Over the last 9 months I’ve gained 20lbs. Which I’m

Not happy about at all. Weighing at 170 just felt like a bit much to me. A couple months ago I started completely watching what I eat and sticking to a strict 1400 cal diet, and working out cardio and light lifting high reps low weight. Well nothing really changed I didn’t notice any difference. Well I found out I was pregnant and have had awful all day sickness so I haven’t been to the gym in 3 weeks. Today at the dr I found out that I’ve gained another 8lbs. 8lbs In 4 weeks which seems a little ridiculous to me. This is my 4th pregnancy and I have always gained the recommend 25ish pounds. I am so scared that I am going to become so unhealthy that I’m going to put myself and the baby at risk for gestational diabetes or high blood pressure. My dr was really empathetic today and said that she didn’t think it was an issue. I’m just so disappointed. Has anyone else gone through something similar ? Do you have any advice? I want to get back in the gym but I feel so sick. I just really want to be healthy.
