First run to the hospital but no baby

Well I just got back from being monitored at the birth center.
At about 10 this morning I started feeling like I was going to start
af and was having a lot of lower back pressure. Then at between 11am-12pm
I was having contractions every 15minutes. This continued through
lunch and I thought maybe I should call my ob (who by the way I saw at
7:30 this morning!). I had asked her this morning about her process
for internal exams and she told me she doesn't find it necessary to do
so unless I wa feeling like I was in labor or if my water breaks. She
didn't want to put her patients through that uncomfortable process.
Fair enough. So at 1:00 I decided to call her and let her know what
was going on. She had me come right over, did an internal exam which
I DO NOT LIKE! She said my cervix was soft, still long, and something
about her fingertip. It was then that she sent me to the birth center
for monitoring. I was def having some pretty big contractions every
11-15 minutes. I got there and all hooked up by about 2pm and was
monitored until 4. Hubby got there just 30min later. He left work
when I told him what was going on, even though I knew I would be sent
home. The nurse had me leave a urine sample at about 3:30 and
immediately said it was way too concentrated and I was dehydrated
which was more likely the reason I was contracting. I downed some
water and the contractions started spacing out. She did check my
cervix which hadn't changed since my doc checked it. She said it was
extremely soft and I could go any time but they'd like me to wait at
least until the end of the week so I could be considered full term. I
just got home, I have my feet up and I keep having to pee from all the
water! I am generally really good about keeping hydrated but for some
reason today I wasn't very thirsty. No infections and group b strep
was negative. The nurse said she has a feeling they'd be seeing me
again real soon. I see my doc again on Monday, my last day of work is
Thursday. That was planned already though. I've been advised to stay
home tomorrow but we'll see. I work a block away from my doc office
and 2-3 blocks away from the hospital. I live 25 min away from both.
I guess I should finish packing my bag and put the car seat in the
car huh!
