Twin Reassurance 😕

Taelor
So just got back from my OB visit and ultrasound. I am 25w 4d with baby girl twins. Baby A is measuring 25w 4d and weighing 1 lb 13 oz. Baby B is measuring 24w 6d and weighing 1 lb 9 oz. Still have the same amount of fluid in their sacs but are sharing a placenta. Both babies have measured right along with each other until this last ultrasound. My OB says he isn't worried but just as a precaution is starting steroid injections. I had my first one today and go back tomorrow for another. I have another ultrasound scheduled next week and will see my OB again. I have no idea what to expect. Have any of you moms expierenced this so early? Should I be worried about TTTS?
