Bleeding for 2 days now

Hi momsh. 2 days na ako nag bbleeding. Kahapon ay light brown na watery, and now, light red na watery. Kakapa TVS ko palang nung 22 and as per utz, 5 weeks pregnant palang ako. 3 weeks late kung ikukumpara sa LMP ko. I already messaged my OB kaso wala pa reply. :( Is this normal? Yung tummy/puson ko, para akong nag sit up, medyo may cramping din na naeexperience. What to do? #1stimemom #firstbaby #pregnancy
