yes, honey it could be a yeast infection..which is normal. I had it too...just go to the doc to have it check..good luck
it also sounds like its abit of old blood which could have come from your cervix, this can happen if you've had sex as the cervix has alot of blood vessels that are close to the surface when you are pregnant, brown blood is old but go and get yourself checked out just to make sure
I would call your ob but the tightness that isn't painful are Braxton hicks contractions which are practice contractions.
ok my stomach was tightening and loosening earlier on today but it didn't hurt.
I agree, you definitely need to be calling your doctor and getting looked at. Ask them if they can do an ultrasound to measure the length of your cervix and check if it's open or closed.
It could be an infection or you could be trying to go into preterm labor. Your best bet is to get ahold of your doctor or call labor an delivery.
you need to call you doctor and ask him...to be on the safe side
