Help! I'm nervous

Hi everyone, let me tell you a little bit about my past cycle. Based on my cm and positive opk I ovulated, the. 6dpo-7dpo I had faint pink bleeding. Missed my Af. Now yesterday  I am at cd53 I bd with the husband and right after it was like a ton of Bright red blood when I wiped, it lasted until this morning but was very little amount. Now, this afternoon, completely gone. Nothing. I'm starting to feel scared. I called my doctor a week ago and she said wait to do blood tests. Help!
