I always thought i'd have children one day. XH had been working from home earning nothing for two years and I suggested that it had been a two year experiment so it was time to work again. He suggested we start a family and he'd be a SAHP. I had a career I was really succeeding in. My mum had taken 7 years and seen numerous consultants before conceiving, my sister at that time had been trying for three years. I conceived first month thinking it was a few years off still.
It was a real shock. Like you I had bleeding at 7 weeks and a real flood of messed up emotion. Actually, bleeding carryed on until about 13 weeks. The guilt I felt about thinking this could be it or have I somehow made/ willed this happen.
All the time I was ment to be delighted. My parents were over the moon, first grandchild, my sister was puting on a brave face. Inlaws full of wanting updates. I was working full time not like all these other people sat around at home thinking about having a little grandchild to play with and offering me lots and lots of advise by phone when all I wanted to do at the end of the work day was sleep. Thats to say nothing of the gentle critisicm about what I was eating, the hours i was working, names, returning to work after etc etc.
Getting my head around just being pregnant and feeling, very rarely for me, not completely in control was a horrible emotion.
With the wonderful benefit of hindsight, I don't actually think for once in life, pregnancy is a time you need the answers.
It sounds like you're really on the ball with contacting your GP and I hope your midwife can support you with the right way forwards for you. You do have the complete right to control your body. Mumsnet has seen me through some of my darkest times and theres almost always someone here who has a shared sense of experience and can relate to where you are now. Theres also always people who'll handhold and help you find your path forwards.
For me having DC has been life changing. I ended up giving up work and now have three children. Whilst I knew before DC about sleepless nights and grizzly children, I didn't know or grasp how some of the other bits would amaze and overwhelm me. Like when you look into a babys face and they stare right back at you as if into your sole. Those moments for me are like complete inner and outer contentment. When your DC achieves some thing that millions, no billions have achieved before them (like rolling over, crawling, pulling themselves up) you'd think they'd won the nobel prize for the level of proudness I feel.
On a lighter note, we flew on a plane at Easter with our three - who managed not to cry. However a baby, maybe 6 months old, sat across from us was unsettled for a short while. Mum took him to sit with dad at the back of the plane, we were near the front. Now she was a switched on parent as she sat back, played on her tablet and enjoyed a glass of wine. Once they arrive it suddenly becomes a shared responsibility it doesn't all fall to mum.
