Spot of blood at 5 weeks dpo

Malina

This is the first time I have ever gotten a BFP. I had taken a test a week ago. I’ve been taking tests frequently and they all come out positive. I am a couple days late for my AF and I have minimal cramping. I had wiped down to see one spot of blood. Tried wiping more to see if it would pick up anymore. Nothing else had come up. My husband went back into training for the military so I have not had any sexual intercourse. Any ladies have an issue similar to this? Just very worried now.
