Maysiebelle, I'm sorry to hear what you're going through.
I had a miscarriage at 4-6 weeks , we can't be sure of the dates(I didn't know I was pregnant as I'd come off the pill and hadn't had a normal cycle- but was hoping and trying to be). This finished about 2 weeks ago now.
I was exactly where you are three weeks ago- I even posted a very similar message. I didn't realise there was so much uncertainty involved. One day my GP was talking in solemn, certain tones about "the miscarriage", then at the hospital they'd bang on merrily about "the pregnancy" and talk about doing scans to see how it's progressing. In my heart I knew it wasn't progressing at all, but you cling onto any shred of hope, don't you? I think you're right to trust your instincts on this.
Meanwhile the physical trauma is really tough, as you know. I hated hated hated not knowing what I was going to find when I went to the loo, and how immobile I felt thanks to the heavy bleeding.
I'm not saying all this to make you feel worse btw! I'm getting to the point... which is that now, a few weeks later, I have truly put the confusion behind me. I felt strangely relieved when finally, FINALLY, a doctor said to me "no you're not pregnant any more, yes you're having a miscarriage". Then today I had my final blood test which showed that my hormone levels have dropped to zero. Physically I'm nowhere near as tired, and there's no bleeding at all.
Like all things, this too shall pass.
Of course you'll have the aftermath to deal with- personally I feel quite pragmatic about things but I know that some women really mourn, which is of course fine (all reactions are fine). But just know that this immediate frightening confusion and darkness will pass and one day soon you'll know what's going on with your body.
Take care in the mean time
xx
ps My partner didn't understand at first but found that it hit him more as the weeks went on. My advice would be not to have expectations of him (other than to look after you) and he'll get through it in his own time.
