Wiped at 30 weeks and saw a small amount of blood?

I always make a habit to look after I wipe since I’ve been pregnant as well as check the toliet . Usually there is nothing interesting but this morning I wiped and saw a tiny amount of smeared red blood. This scared me a little bit because I’ve been so used to seeing nothing .

Of course looking online will send you into an actual panic . Just as an FYI I didn’t have sex or anything , I eat clean and take some pretty good female probiotic so I hope it isn’t a UTI , I haven’t had any contractions but I do get mild cramps some nights .

I’m going to call my ob gyn as soon as the open but I was wondering if any of you ladies have seen something like this
