I am 19 and my period was late in January and it was pink and I started getting pregnancy symptoms in February and my period didn't come but it came on March 7 which makes my period 7 days late and it was normal. I got my period Monday and it is red and watery. I'm still having pregnancy symptoms. I have taken 5 pregnancy test and 4 were negative and the fifth had a faint pregnant line that went away quickly.
you could be pregnant. try to check an OB
