Engagement Pic Advice

We are finally getting around to doing our engagement pictures on the 20th! I'm not a picture person... I hate taking pictures right now because I'm not comfortable with my body right now. I had gotten up to 190 lbs about 2 years ago due to complications with my endometriosis. I had a major surgery and dropped to 160ish within about 1 month following. I ate very strict anti inflammatory diet and felt better than I had in a few years and was dropping weight at a safe rate. I was down to about 150 when my FH and I began dating... which still was bigger than I'm used to being but coming from where I had been I was happy with myself. I'm only 4'11" and I'm used to weighing between 120-135 at my heaviest under normal circumstances. Of course, once I started dating him I began to put on a little "happiness" weight lol. Now I'm back to 160ish.... and I hate it. I am not one to try anything extreme, chemicals and stuff like that do not work well with my body so when I lose weight it has to be the healthy and correct way. I'm working on losing weight for our wedding in June 2021 but of course I'm not going to lose 30lbs before engagement pics. Any advice on clothing or poses to make me not feel so self conscious? My FH is just amazing, he loves me just how I am and always compliments me and makes me feel beautiful. I'm not a girly girl, so I'm not really big on fashion and stuff like that and it's also really hard to find things that fit me right being so short. I'm not crazy about dresses and getting all dolled up but will do it on occasion. As a matter of fact, the one and only time my FH has seen me in a dress was this past May on his birthday... it was a surprise to him and he absolutely loved it, but I really don't feel comfortable in dresses. I'm really dreading this photo shoot, and he is excited about it so any help or advice is appreciated!!
