Am I too big to get pregnant? 🐬

I<3Dolphins • I`m a 23 year old Military wife. My husband and I have been TTC #1 since November 13, 2013. ✨
I'm posting several pictures and I was wondering if you think I'm too big to get pregnant? The doctor said that I should lose weight before I get pregnant. 
I usually only take pictures of my face so it was hard to find pictures of my body. Lol. 
I am starting to eat healthier and exercise.  But I don't want to have to lose all the weight before I have a baby. 
We have also been trying for almost 2 years with no luck. Does anyone have any tips? (Besides 'relax' or 'don't think about it'). Lol. I'm working on those. 
Thank you! 🐬💖
