Has this happened to anyone?

Last Friday I got a positive hpt. Monday I started bleeding. Went to the ER they thought I was lying because their urine test showed negative. They did blood work. Turns out I was pregnant. Beta was 24.1. Monday evening I started passing tissue and clots. Passed a little more tuseday and still bleeding very bad. Wednesday evening bleeding tapered off had another beta it was 34.1. Thursday didn't bleed at all. Friday (yesterday ) I started spotting and my beta was 62. Today not bleeding and have to go tomorrow for another beta. I am so confused and worried at the same time. If this is a muscarriage I just want it to be over with. I spent 8 years saving for my tubal reversal surgery and have my dream come true of holding another blessing in my arms and to only have this happen. I know there's always next time but my heart is broken and I just want this to be over. I don't want it to drag out. I have no idea why my numbers pretty much doubled. That's the confusing part because I've passed everything, I know I have I seen it. So why would my numbers double? I am hanging on to a small thread of hope and feeling like I am going to be left broken again.
