Okay, so, my name is Nicola. I am 16 years old and right now, as the name of my thread suggests, I have a big mixture of curiosity and fear right now. You see, it's now the 29th of July, and there has been no sign of my period- well, in terms of bleeding! You see I've been having some painful cramps, as well as that crampy-icky feeling that I get in my stomach, but no sign of bleeding. As you would imagine, I am kind of worried by this. My boyfriend and I have been together for a year and 4 months now, and for about 3 months we have been having unprotected sex on and off- when he has a condom we'll use one but when he doesn't we won't. I know this is foolish, but he insists that it's okay, that he'll pull out in time. He also likes it better without a condom because it feels nicer. Anyways, getting back to the point, I have also had some worrying experiences this month

A few times now when I have been in the shower in the morning, I have started to feel really nauseas and dizzy, and have felt like I was about to faint, so I have to sit down for a few minutes to try to regain myself to get OUT of the shower.
Also, I have been having an exremely painful, well... pain, in my lower stomach, that has been to the point where I can't walk until it goes away. However, this COULD be due to the fact that during this summer I haven't been waking up till around 11, and the first thing I do is have a shower. Normally by this time I would have at least have breakfast, so it could possibly just be a sign that I need to eat- and soon! but I'm not entirely sure.
Furthermore, earlier on this week I was at the nail parlour with my mum to get our feet done, I started to feel really warm, and my stomach felt awful, then I started to breathe more heavily and got what I think would be considered a black out, since... everything went black,and I could see for about 30 seconds. Of course then the only thing that I needed was a washroom, where I ended up throwing up... it wasn't pleasant
So the jist of this email is that: IS there a possibility that I could be pregnant? or is the fact that my period hasn't come yet possible be due to stress? Also, what are your guys thoughts on the pains that I have been having, and the cramps-but-no-bleeding??
thankyou for reading this and I hope to hear a reply soon!!!
