Hcg 30

Latoya

I have been experiencing light pinkish blood only when I wipe. Sometimes I feel cramping all over but it’s very mild and it comes and goes. I totally feel pregnant but I went to the ER and they said because my hcg is so low and only at 30 that it’s possible I’m having a miscarriage. If that was the case, wouldn’t I be bleeding heavy and cramping more severe?
