12 weeks and still anxious

So I had my first u/s at 10 weeks exactly I'm 12+1 today everything looked good..

I get nervous because this is my first pregnancy I haven't had any crazy cramps but I get these pains in my right and left side a lot. I hear about RLP. But sometimes it's worse sometimes it's not.. idk if it's RLP or if I should be worried I haven't had any actual "cramps" and no bleeding but I still can't help that when I turn the wrong way I'm doing something wrong.. My next appointment is sept 15th I'll be 14 weeks exact. And I think I hear the heartbeat that day. But I'm still nervous. Any ways to help with my anxiety about it?
