lots of BH contractions

i've been having a lot of BH contractions since yesterday around like 7pm. they are not at all painful although a few have made me kind of out of breath, and they don't go away when i sit/lay down/etc. im assuming i was having them while i was sleeping because everytime i would wake up in the middle of the night (as i do often), i'd feel one happening.
my doctor told me to go in if i've had more than 5 in an hour.. i'm pretty sure that ship has sailed. but once again, they aren't painful or regular or anything. is it probably nothing?

If you have had more than 5 in an hour I would do what the doctor said.

It can go on like this for days....weeks....sorry.  
The good news is this gives you a good time to teach yourself to relax, breathe through them and get your mind trained to get past them.
You'll know they are real when no matter what you do they wont go away. Like if you lay down, rest, take a shower or relax adn they get easier or subside then they are BH. They are real when no matter what you do they come at regular intervals and do not subside. It IS normal for BH to vary in strength.
Walk walk walk, have sex and make sure everything is packed.
