Question???

Ok so I have an almost 2 year old and have been under a lot of stress. I live with my bf and we have been having a lot of sex lately. Ive been off bc for 2-3 months but we use condoms. Well the last few days I've noticed my boobs have been hurting and I've had a sticky, clear/white discharge and also certain things have been making me feel sick and today I had a headache, my question is does it sound like I could be preg? I'm not due to have my period until the 8th and I has my period last month.
