37 weeks and woke up to wet sheets with pink

I was checked yesterday because I thought my water was leaking but my doctors said no but that it wasn't urine because the fluid was clear. I woke up this morning and my calves and ankles are swollen but I also woke up to wet spots on my sheets with pinkish/bloody fluid spots. I had some cramping last night but nothing currently along with no more bloody or pink tinged anything... I called and my doctor said this is normal?? And if I have more or bleeding to get checked... should I be concerned and go to the hospital anyway? Is this really normal? Baby is moving and I checked my Blood pressure on my cuff at home and it's fine ( 122/79 ) I am really nervous I haven't had sex, I know it wasn't urine (smelled it and I have white sheets)
