I felt flutters last night!💜 (anyone who is going to be rude, don’t comment)

This may be stupid but....how long do contractions last for? I keep having period cramps and lower back pain but it lasts like 3 minutes each time.

Science!

My friend posted this on facebook last night and said her kids were asleep within minutes. It's a song that scientists created to help people fall asleep. I was skeptical but I thought what the hay, I'll try it out. I didn't bank on Dh falling asleep, but both him and lo were asleep by minute 2. And lo slept six straight hours. ?

Got to the hospital at 4 am to start my pitocin, well.. I was put on the drip at 430 am , and was 4cm dilated and 80 percent effaced, an hour later. The nurse came in to check me, hours later, and I was at 6 cm. I got the epidural at 6cm.. But it didn't work for me, no more than 20 minutes later, I couldn't take the pain, I was screaming and crying.. And felt everything.. most terrible pain ever, I called for my nurse to come in and she checked me again, said I was ready to deliver, babys head ...

I keep getting this weird sharp pain right below my tailbone.. Anyone know what it is? It comes about every 45 seconds to a minute and lasts like 5-10 seconds.
