Haven't Grown in 4 Years + Bad Period Pains

Hi, I am not sure if any one is able to help me but i thought i might give it a shot.

I am just over 17 now, female. I am 168cm (5'6") and haven't grown in approx. 3-4years. I was late in regards to puberty. My period has only just begun to settle down. I have gained a bit of weight (fat) (in addition to weight one expects to gain when puberty hits) over the past few years and no matter what i try i can't seem to shift it and in the past few months i have gained more. My questions is - will i grow? and why haven't i grown?

Also, I have incredibly bad pains. I am thinking they are related to my period but am not 100% sure. It starts off like a cramp with a slight difference. it progresses - becomes worse with more severe pain lasting longer. I then spend the next little while on the toilet (minor diarrhoea). The pain gets worse. My mouth fills with saliva and becomes agitated. I then feel like I am going to faint and vomit - black closes in and the recedes. It lasts for a few hours and then goes away. Sometimes it results in vomiting. Sometime nurofen (pain killers) helps to subside it.

I really hope someone can give me some answers I really need them. I have seen someone about the second issue and though it was resolved but isn't

Thank You.

ok for the first issue its posible you have stopped growing. i have been the same height since 6th grade and i am not a freshmen in college. im not complaining i mean i like my height since im at 5'3" but anyway for the second one it sounds pretty extreme and you may want to go to the doctor for that. if it is from your periods though try eating bananas it usualy helps but i do recommend medical attention. also if you are trying to lose weight ( not sure if you are just throwing it in there) cut out all junk food as well as pork and substitute it for more fruits and more vegetables. its not really considered a deit because you are still eating its just eating healthier and taking everything that turns into useless fat and things your body doesnt really need out of your body
