UPDATE!!! Empty sac and spotting

So I realize my chances of success here are slim. But I can't sleep so I figured no harm in asking if anyone else has dealt with this.

2nd pregnancy. But 1st was terminated early 7 years ago.

Based on my last period, I should be about 8 weeks. But Sunday evening, I started spotting. Very light pink. Not enough to get on my underwear at all. Still worried though. So we called the doctor Monday morning and spoke to a nurse who said to put on a pad and watch it. If it gets heavy enough where it's getting on the pad, call back.

We had an appt for Wednesday morning anyway for the first appt (we had one a few weeks ago just to confirm pregnancy, which they did from a urine test. But didn't do any other testing).

So Monday and Tuesday the spotting pretty much stayed the same. I happen to have the week off from work so I rested both days and never had evidence of blood on the pad. Though the color did change from pink to red.

Yesterday morning we go for the appt. Do an abdominal ultrasound and can't see anything. Vaginal shows an empty sack.

Doc explains that with the spotting and empty sac, I'm likely looking at a miscarriage. However, that it isn't 100% because I could just not be as far along as I thought. They took blood to test for hormone and were going back Friday to test again and compare.

They did not tell me how many weeks the sac was measuring. Maybe they could tell I was panicking, who knows.

The rest of Wednesday my husband and I were of course devastated and started filling our families in on the update.

I'm still bleeding, and it is still red and I am seeing small amounts of tissue here and there. But I'm not having any cramping and here it is 4:30am, I went to pee, and nothing on the pad (yes when I wipe though). And throughout the rest of the day I did see some evidence of blood on the pad but only a very little bit. Could've gone all day with one pad if I wanted.

I realize I'm likely miscarrying and it just isn't all happening at once.

I read a bunch of posts with women who had an empty sack and the different outcomes that occurred after.

But has anyone had spotting AND an empty sack, and still turned out with a healthy baby? Just wondering if there's any kind of realistic chance here.

UPDATE:

We just went to the doctor to take second day of hormone levels and got the results from Wednesday. Wednesday I was at 3512. So now I'm just confused. When the doc was going over everything with us Wednesday she said "were looking for numbers in the thousands". So I accepted that I was miscarrying, we called our families. We cried a lot. I've been resting. And when we went today I was expecting a very low number. But today we got that number. Which is normal for 5 weeks, and still normal but on the low side for 6 weeks. And that you'd be very unlikely to see an embryo in the sack at 5 weeks.

I'm trying so hard to not get my hopes on. But is it possible that I'm still doing well and am just 5 weeks instead of 8?

I then tried to just google my physical symptoms because I am still bleeding, and it is getting on the pad but not enough to fill one. And I have passed some tissue, but no clots. So I googled "passing tissue but no clots" and found all these forums of women who even passed clots throughout their pregnancy and still had healthy babies.

Am I just insane at this point? What a roller coaster
