This is my fourth pregnancy so although I don't presume to know everything I do think I have a fair idea of what's normal and what's not so normal.
I am 33 weeks now.
For the last 4-6 weeks I've been getting (what I assume are) braxton hicks contractions. They are really painful and lots of different things set them off - walking, bending, lifting, sweeping the floor etc. They cause my stomach to cramp and I end up sitting on the toilet for half and hour or so until they have passed. They cause me to lose control of my bladder and bowels 
and it can happen anywhere, although luckily only once outside the house or away from a bathroom. I also think that it's caused me to get piles as I can be quite sore and 3/4 times a week there is blood on the tissue. I've been quite constipated too on and off.
It's really affecting my life, I only leave the house now to do the school run and even then its risky and usually involves me getting a taxi back as the pains start and I need to get home to the bathroom as soon as I can. Everything else I do online, shopping etc. I feel quite isolated and trapped, my toddler has started sleeping badly (well worse than normal but he's never slept well) and I think it's because he is stuck in the house with me all the time and is getting no fresh air. I am miserable.
My midwife is beyond useless. She never listens, I feel like she looks down on me, she's dismissive of me, she has no interest in me whatsoever as far as I can tell. I had an appointment last week but I cancelled it as I couldn't face seeing her. Realised I was being stupid and remade the appointment. It was on Monday just gone.
I was embarrassed but told her about the problems I was having. And she shrugged and said "that's an elderly persons problem, not something someone of my age needs to worry about" and that I should've done more pelvic floor exersizes in the past - but no advice on how I could actually get my life back.
She was also annoyed that I hadn't gone to the next town to where I live (20 minutes by bus so not far) and had my blood tests done in Boots. I tried repeating to her that I was having trouble with walking and hasn't been anywhere but she just glared at me and huffed and puffed that she would have to do them herself now. She took the blood (as she had all the equipment with her) and moaned that she would have to drop them to the town centre herself now and she would've preferred not too.
I left the surgery in tears of embarrassment and frustration.
I asked at reception about how I could change midwives and if there was anyone else at the surgery that I could see. She said she was sorry but the midwife didn't work for the surgery and only rented a room from them. She suggested I call the number on my notes but it is the midwifes mobile number. I'm scared to try and find another number to ring about changing midwives incase I can't change and it gets back to her that I wanted too. I'm tempted to change gps surgery and hope that I see someone else there. Or, can you opt out of seeing a midwife at all and see the doctor instead?
I'm sorry this is so long, I'm just feeling a bit fed up. At least I don't have to see her again for 4 weeks!
