Started pretty much every 30 mins then i would go 30, 10, 20 and just random combos of those. In between Im getting conatant backache and lots of BH. Im currently about 25 mins however I still keep having the odd one after 10 mins. I feel completely drained, they arent so so bad but when I get them I cant stand up straight. Eurgh will they just get closer together over night?
