I don’t want to be dramatic and go in if nothing’s wrong, but I don’t want to not go in and have something be wrong. Pregnancy is hard!

I’ve had cramping on my right side under my ribs since about 3pm (it’s now 8pm) and every once in a while it’s a sharp pain. The baby feels balled up on my right side. He is still kicking but all kicks are on the right side. I’ve also had a bad backache the last two days. I’m slightly constipated but have been able to go a little each day (sorry, tmi). I don’t know if I should be concerned and go in or if it’s just constipation cramps?
