My teeth have been more sensitive too, didn't really think about it though until just now lol. My boobs are super veiny as well as my sides. I'm hoping all these symptoms mean the little bean is gonna stay with me... Thursdays US can't come soon enough.
And I'm the opposite, I haven't noticed any new veins and my nipples haven't really darkened at all. I already have stretch marks from gaining a lot of weight as a teen, but so far my doctor isn't concerned about my weight. She thinks I may even weigh less after the baby is born than I did when I got pregnant.
My nips aren't darker either, in fact that had never happened to me. The areolas are a bit larger though, which usually happens to me.
Its definitely possible to lose weight either while pregnant, or shortly after.
With my first son, in 2 weeks after birth, I was 5 lbs less than before I got pregnant.
With my second son, before I got pregnant I randomly put on weight that year. Kind if like this time. I ended up by birth having only gained like 5 lbs, because what happened is my weight shifted. So I basically looked like my normal size (before weight gain) but with a pregnant belly.
Apparently that's already starting to happen again. I have technically gained 2 lbs due to bloat, but everyone us asking me if I'm losing weight. Also, besides the waist, my pants are looser. Idk why I gained that 25 lbs out of nowhere months ago, then got rid of like 10, but the extra 15 stayed....
A lot of times its because your thyroid goes into over drive while pregnant.
Years ago while getting a lot if testing before being diagnosed with graves, my doctor was extremely b interested in everything that happened to me after my youngest was born. Apparently he thinks I had acute thyroiditis, common after birth and usually resolves on its own, but for me he thinks it triggered the graves disease, something that was going to flare eventually, but giving birth turned it on. I also lost weight very rapidly after my second was born, it was almost scary. I literally didn't do anything to try. Now I know it was probably cuz I was hyper thyroid.
All I have left if my thyroid now is a teeny tiny piece on each side, just enough for the para thyroid glands to stick to...but apparently even those little pieces can flare while pregnant and cause problems...so I have to have my levels checked constantly
My bbs are still a little tender but not as much as they were earlier, I still have cramps too but not as intense as before. I feel like my symptoms are slowly going away 
I guess if this isnt out month at least I already have a doctors appointment for a week from today so maybe they can give me some advice on what to do next!
