Hi! I joined this forum as I didn't know what else to do and I thought that I would find the help that I need on here. I am 16 years old (nearly 17) and I don't know if I am pregnant. I am currently on the injection (depo) so I don't know if my symptoms are side effects of the injection or are symptoms of pregnancy. I have experienced random brown discharge today, I've been needing to go to the toilet for a wee more often than usual and ive also been suffering with constipation. My breasts have also been very sore and I have noticed they have grown a little. I was just wondering if anyone could offer and advice, help or support.
