HCG Levels dropped - how soon will I MC?

Tara

About 5 weeks along, took Beta HCG last Thursday, was at 140. Took another hcg test almost 72 hours later and it was at 50 so my doctor told me that it’s a chemical pregnancy and I should just Make it pass naturally. It’s been heartbreaking but I have not felt any cramps or experience any bleeding. How long did it usually take for you ladies to begin bleeding? I’m really hoping to try again right away.
