when do you start feeling symptoms of pregnancy?

 Ok so I'm almost 8 weeks PP. I've been having protected sex, but obviously anything can happen and I'm super paranoid. I looked up when symptoms start and all it said was this, but since my period hasn't exactly started yet.. I don't exactly know what this means lol. I think I'm just being paranoid and I'm just about to start my period for the first time maybe. But I've just been super emotional and have been having really bad cramps and boobs have been tender not really anymore but the other day they were. Just need someone to tell me I'm being paranoid and I really am just about to start my period. I also bled for 6 weeks so we really didn't start having sex until then.
