Even at 5ft 2", you don't need to be 105 lbs. You may be viewing some of your bodyshape with very harsh eyes and judgement and being a little unfair to yourself as well.
You'd be more advised to build up instead. Being 115-120lbs of lean composition, would be a really good thing for the future. The extra strength and the associated training effects on your bones and connective tisues, would really help.
Plus when you're over 50, the effort required to be like that, would slow down the rate of physical decline, hopefully stopping you from getting things like lower Back pain, joint pain and Osteoperosis when you're over 70, because I read once that 1 in 3 females over 70 or 75, I forget the exact age, have Osteoperosis, which is a staggering figure and what you do now can help you in the future.
Plus you must remember the effects that how you train and eat, have on your internal workings too. You can't see what your Bones, Cholesterol, Blood Pressure etc etc look like, so you can't expect to be a certain ideal weight and hope that it is a healthy way to be, on the basis that you might look healthy.
So don't start to spoil how you look by being a little underweight. Wanting to look your best for your special day is important, but there's a fine line between getting down to the "looking at your best" stage and going past it, to the point where you start to detract from that look.
Trust me when I say you are a beautiful looking lady and you're marrying a good man, so don't be hard on yourself regards appearance, because you don't need to be and if you get too hung up on it, you might start getting too low, on the weight, trying to persue a level that isn't good for you.
You will truly and honestly look fine. You look quite breathtaking in all your wedding dress photos and your future hubby would probably prefer his wife, to look in healthy condition, not a little underweight I would imagine and if you had another lean strong inch on the Arms I'm sure he'd be the kind of guy to support you or even want to train with you, because you can see in the photos that you and he have such a natural loving connection, so whatever you do, don't give him a reason to feel less towards you physically and don't let any hang-ups about your weight, threaten to cause dischord within the relationship, because you have something that can potentially last a lifetime.
You CAN love yourself for being you and you deserve to as well. You CAN be proud of what you have done thus far and you CAN keep it up and you CAN make it work for you, but don't be pre-occupied with slight "overkill" weight targets. You've gotten to 110, so maintain that for 2 weeks and don't worry.
If losing that extra 5lbs, makes you look a little unhealthy in the wedding photos, you'll spoil some of the memories and looking at the one of you at 120 lbs, which isn't overweight at all, you simply glow and you look really healthy and vibrant and striking.
So just keep making sure your diet and training are on song and don't worry about that 5lbs of weight, because it may just tip the way you look over into the "verging on unhealthy" look, which you don't need to go too.
You look incredibly feminine just the way you are. You and your man definitely deserve each other, so chin up, keep smiling and no worries okay.
You WILL look just fine, you really will and you deserve that special day of yours, because you're a pretty special person.
