Bella
Writing it as I feel it, the thing is that I just started my period, and I feel terrible, I have nausea,diarrhea, but ok, it's gross, but it's like air, and my stomach hurts, and I feel like I'm going to throw up, and my eating habits are not that good, and today I ate carbs, and a piece of cake and I usually don't eat sugar, and I just feel terrible and I don't know what to do, I'm not pregnant, and I'm 16, and my first blood stain is kind of black-ish, and right now in his drinking some chamomile tea, and please, can somebody tell me if they go through the same, or if they know something I can do about it, because as I said, I am feeling terrible and I hate it 😭😭😭😭
