Hello,

Am looking for a little help am 18 and live with my boyfriend we are quite sexually active and recently I have noticed i am starting to get a bit of a belly and am not sure if I am just putting weight on or if I am pregnant I have read online some thing that happen to your body when your pregnant but am not sure if this is accurate or not because I have been getting a little pain in my lower back the last 2 weeks (not sure if this was because my period was due or not) I am always thirsty and getting sore headaches quite often (not sure if it because I work with computers or not) however am just not sure and it's stressing me out because I don't want to do a test incase I am if anyone can give some advise I would appreciate it a lot thanks x
