Hi, I had a a silent miscarriage at 8+1 weeks although this wasn't detected until my 12 week scan. I had a surgical procedure to removed the tissue around 2 weeks ago but I'm still getting positive pregnancy tests. I took a clear blue digital test today which shows 1-2 weeks pregnant. I suppose my question is how long does it take for levels to be undetectable on a test? And is it possible to ovulate with detectable hcg levels? I was to ttc again asap which is why I ask. My midwife told me to wait till I have a period before trying again but just want to know if its possible to get pregnant again before hcg levels go to zero. Thanks in advance.
