I am 7w1d pregnant and around a week ago started spotting brown discharge. The last few days this has gradually increased in volume and changed to red blood like a medium flow menstreul cycle. Not experiencing any cramping which is somewhat reassuring. Yesterday I passed some tissue like looking substance which looked a bit like the picture below. And then I passed this (pictured) again this morning. Yesterday I thought i might be miscarrying and the tissue pictured might be a sac... But find it odd that I have passed the same thing again this morning. I have read in places it could be my womb lining but I don't know. I have a scan tomorrow morning but am so anxious and just want to know if anyone else has experienced anything like this please?!!
