So I had some light bleeding 2 days ago only lasted one day then turned brown the next day and seemed to stop yesterday. I had an early scan this morning which showed Im around 5 weeks and that the sack is in the right place. They said they cant see anything, no blood in my uterus and that it may be implantation bleeding. No bleeding today, but now ive just been to the toilet and there pink blood again. Does implantation bleeding start then stop? Im so worried which is horrid as I came home from the scan feeling so reassured. Any stories welcome, thank you!
