Contractions

Nichole
Can any of the mommies in here that have had there twin tell me about contractions?  I have had two singletons and know what that feels like. But am curious if it is the same with the two I'm having now. I feel a lot of pressure and tightness. I'm 34w5d I have an appointment today so I'm not looking for any medical advice just experience.  I have a real high pain tolerance which can work against me at points. Thank you for reading
