So I thought I had been experiencing braxton hicks since about 24 weeks, tightenings across the middle/top of bump... Now I'm getting cramps, especially in the morning when I wake up .. very low down and feel exactly like period pains. Has happened 3 days in a row now, and also happens throughout the day but not as strong. It can be really painful in the morning and spreads round my lower back... are these BH too? What is it?!?!
