Has anyone ever gotten faint lines, bleed like a chemical pregnancy happened, but ended up not having your next period like your body still thinks its pregnant?

I supposedly had a chemical pregnancy just 3 1/2 weeks ago. But, I noticed lately that I've been getting acid reflux and heartburn. And its just one of those things that I NEVER got until I was pregnant. Literally, never had either of the 2 unless I was expecting, only time.

I'm gonna make an appt with my ob/gyn soon and see what they say. I would just like to hear other peoples stories.
