***TMI***

So recently my vulva area has been very itchy and has been burning so bad. I have been itching it like crazy. It hurts when I pee and I pee every 20 minutes (ugh pregnancy🙄). Anyways to relieve the itching I put on some cream stuff that my mom recommended and it has been helping. I used a panty liner so the cream wouldn't get all over my underwear. When I went to go pee I looked at the panty liner and noticed the smallest amount of blood. I instantly got worried. After peeing I wiped and there was no blood anywhere. Am I spotting or could it just be from itching. (Mind you it wasn't bleeding before and I hadn't itched it for a good two hours) I'm 28 weeks and 4 days pregnant. Is it normal to spot this far along even if it wasn't from the itching. Let me also mention that I have been having sharp stabbing pains in my pelvic region and a lot of back cramping for about two days now. It's no where near enough blood to rush to the hospital or even call my doctor (I have an appt Thursday and am just gonna wait till then depending on the feedback) I'm kinda worrying and need someone to calm me down. Sorry if this doesn't make sense. Has anyone else experienced this?

UPDATE:

I posted this the other day and didn't have any more bleeding or spotting so I thought I was fine. But just now I was taking a nap and I got a very sharp pain in my pelvic region that woke me up. It went away and I went to the bathroom to pee. As I sat down I saw more blood in my discharge. It's still not a lot but it's more than last time. And it was fresh. Not dried up. Has anyone else had a similar experience?
