Needing some Reassurance please....

Is it normal to have spotting off n on??? One minute I'm spotting n then I wipe n nothing. Haven't had sex for a minute either. I've had 3 miscarriages afraid of something happening. Anyone having this problem or had this problem n everything was okay??? 11 weeks tomorrow. Had my miscarriage at 11 weeks n 3 days too. So I'm kinda freaking out too.
