Won't cope with 3 months of this!

Since Sunday night I started having intense Braxton Hicks and they were as many as six in 10 mins.. So I went to the hospital and they sent me home after 7 hours because I felt better after lying down. Then yesterday all day my uterus kept tensing up and it hurt to walk or get up from sitting. It was no better today so I went back to the hospital and this time they examined me.. The cervix was closed and the fibronectin low so they said the risk of preterm labour was low but still no answers on why I'm getting tightening every few minutes especially when I move. It's been a very stressful few days. I'm beginning to think maybe I just have to accept this!
