You obviously have some doubts & concerns, for that matter alone it is worth getting checked out.
I was showing protein for 4 weeks (tested every week) and headachy, throwing up, swelling etc & my midwife did NOTHING except keep making me appointments with her.
Finally she asked a co worker what to do, who said 'get her to the hospital' only for the midwife to completely play it down, by saying 'I think we need to refer you to the hospital' quite calmly. If I hadn't heard the dr myself, I would have waited for a letter form the hospital, as it was we were both concerned enough to insist to her, that we go straight to the hospital.
On arrival my BP was high & I was monitored for a few hours, wee samples, bloods taken. I was sent home to collect 24hrs worth of urine, which I dropped back to the hospital. They called me that day asking me to go in for a chat. My BP was sky high, I had too much protein & I bloods were showing signs of concern so they wrote 'deliver now' right across my notes. The consultant actually said 'bloody hell' when the nurse read out my bp to him.
I didn't leave the hospital for a week & my baby came that night, 4 weeks too soon & weighing 4lbs.
If we hadn't insisted on going down that day, instead of waiting for a letter/appointment, I don't want to think about what would have happened.
So no, I do not recommending trusting your midwife. They do get it wrong. She was an older midwife, so had heaps of experience, yet still didn't know how to deal with my symptoms & never once, over 4 weeks, gave me cause for concern.
If YOU are concerned, do something. No one knows your body like you. Trust your instincts, please.
