Okay, seeing vein on your chest is normal. How do you think the body is supplied with blood? Through veins. sometimes they are more prominent on other so that is nothing to worry about.
Nipples changing colour is also normal. As you grow your body changes this includes size, shape and colour of nipples.
Most women experience nipple tenderness from one time to a noter - and yes it can get so bad that it hurts to lay on your stomach. try warm water baths to sooth them.
If you are a virgin then there is no chance that you are pregnant. even if you kissed someone you would have to have sex in order to get pregnant, so dont worry.
Vomiting is a sign of pregnancy but you would be vomiting almost everyday for 3 months in order for it to be a symptom of being pregnant. not just every now and then. you may have vomited for a great number of reason i.e a bug, food poisoning, virus, flu etc.
when you first get your period it can take a while for it to come regularly. I didn;t get my second period for 3 months. its perfectly normal.
Once again, if you are not sexually active then you arent pregnant.
there is nothing wrong with being embarrassed to about talking to your mum but I honestly dont think there is anything 'wrong' with you. just hormone changes. talk to your mum but if not then go to the doctors by yourself.
Hi,
I didn't take the time to read the rest of the replies. I will say, though, that I'm 39 and I have been able to see one particular prominent vein in one of my nipples since I was your age. I wasn't pregnant when I first saw it, and it has stayed with me through multiple pregnancies and beyond. I've had mammograms and no doctor has ever seemed worried about it, just like I've never been worried about it. It's normal.
As for tender breasts or nipples, those are very much associated with puberty and the growth of breasts you go through during this time. They will stop being sore with time, I promise, except right before your periods.
