I don't even know what to title these posts. I'm not going to hold back much so this may be TMI or upsetting, read at your own risk. Thank you all for the comments, I have read them and they mean so much to me.
The spotting turned into light bleeding but never got to heavy bleeding or lots of clots. The cramping was uncomfortable and Advil worthy, but not as painful as the worst cramps I've experienced on a normal cycle. I had a hard time falling asleep, my mind just rolls around about all of this, but I think I fell asleep around midnight, woke up again around 1:30 and the cramps were gone. Slept again until a bit past 4, still no cramps but I did have to pee and I was hungry. Again, some blood, but it was thin and not too bad for 5 hours. Fell asleep again around 5. All in all, a pretty restless sleep.
The cramps came back around 8:30 or so this morning. Bleeding is light and turning brown rather than the bright red of yesterday. I'm starting to find the cramps are coming and going now so maybe things will settle.
I went to the clinic this morning, I did have the 9:30 appointment for intralipids. They sometimes go ahead with intralipids because bleeding isn't completely abnormal in early pregnancy. In calling my doctor, the decision was to do blood work today to see what my HCG and hormone levels are at and reschedule intralipids for either Tuesday or Thursday if the results suggest continuing. My HCG levels went from 111 to 182 on Saturday. So that isn't quite doubling at 1.64, but it is normal to double within 72 hours and it would have doubled by then.
So for now, my orders are to rest. And wait, and hope.
