29 weeks tomorrow and blood??? plz help

Paige

i woke up this morning and went to the bathroom (#2) and there was a pea sized spot of blood on the tp at least 3 or 4 times (i kept checking) i know for sure it didn't come from my bum.

I'm freaking out as i havent bled this entire pregnancy and have had 3 first trimester miscarriages. I'm 29 weeks and is this normal??? i haven't had sex in like a week if not more
