What pregnancy symptoms did you have?!

Me and my boyfriend have been together going on for 3 years! I've been having sypmtoms like lower stomach pain,and the side of my vagina on top has been hurting. I woke up in the middle of the night very sick and lightheaded. I got my period but it was different,it was brown and I don't think it was as long(some people still do get their periods) I was just wondering if anyone was in the same boat,or someone can tell me the symptoms they had. Me and my boyfriend have unprotected sex using the withdrawal method. Thanks:)
