Tell me about your spotting experiences in third trimester please!!

Sasha
I haven't had any bleeding or spotting the entire time I've been pregnant. So to look down and see red on the tp today was a little nerve wracking. Don't get me wrong I'm still calm and not packing my things to rush off to l&d, but I have cramping in the front and back and I've had weird tightening/belly pains while I was at the store earlier. Baby is moving like usual but the cramping and back pain sucks. I tried a heating pad for 25 mins and it helped a little but we're right back at it. Can you ladies tell me about your spotting experiences? Did u call dr? Did you wait it out? Thank you!
