So its 3:37am. I went to bed around 11. Woke up to pee about 5x in that amount of time. Everytime i woke up i had a painful contraction. I have now been up for an hour still having painful contractions. I am timing the contractions but right now they are about 8 minutes apart. My husband and my kids are sleeping and i dont want to wake them until they are 5 minutes apart. I was due yesterday 3/27/16. I really want to take a shower but my bathroom is in through my bedroom and i dont want to wake my husband up. At my drs on Friday I was 1cm & 80% effaced. I have a drs appointment today at 9.
