Currently 35+6. Last night I noticed nipple discharge for the first time (well hubby did, when he saw a wet spot on my shirt 😂😂😂). And I've been having some mild cramping on and off but not consistently. On top of that I had a bunch of mucus this morning but it was normal white color and not tinged with blood. Could these all be signs of pre-term labor? Or just normal third trimester symptoms? I see my doctor on wednesday so I will ask her then, but just think it's weird everything's starting to happen at once!
