Confused.

Ok positive test on 6-5 confirmed with digital on 6-6 and again on 6-9. Started spotting 6-12 pink then brown. Went to ER on 6-14 because it turned red but still very very light bleeding. Beta test 264. Had OB appt 6-15 did labs 3pm - stopped spotting around 9pm that night. Got results next morning - 137. Still no spotting, nausea set it. 6-17 at 9:30am did another beta - 54. Still nausea, sore bbs, watery cm all the time, and round ligament pain - still not a single spot of blood.

What is going on? If i am m/c shouldnt i keep bleeding, not stop? Shouldn't my hormones be gone dropping at that rate? I should be bleeding by now right? Not gagging at smells...
What is wrong with me?
