Hi MK24 I also recently lost my first pregnancy at about 5.5 weeks. I had had two positives, but then a week after the first positive I started spotting and feared the worst. Took a pregnancy test to 'put our minds at rest' and it was negative. I bled heavily the next day, and then spotted for a few days after that.
I completely agree with what Bunny said. It is both heartbreaking and confusing. You are grieving both for an actual baby that you already loved, even though you will never know anything about it, and the idea of a baby that you really wanted. For me it has now been a couple of weeks, and the pain in much less raw, but I think it is one of those things that will always feel like a cruel trick, but at the same time almost surreal. It was particularly hard because we found out whilst on holiday in America (which is my favorite country), and that felt really special.
At the time I couldn't even face the idea of starting TTC again, because it felt callous almost. I have now come to terms with that, and we are actively TTC. I actually now want it to happen as soon as possible, so that it will feel like part of one journey. However I am still not drinking, not drinking coffee etc. because I feel not quite ready to move on, even though I barely had time to start feeling pregnant. It probably isn't healthy, but it helps me maintain a sense of impending motherhood.
I don't think anything anyone says will really help, but I hope you are ok. Make sure you take time to cry and be with family.
