I came off my pill 3 weeks ago and it was the pill where I didn’t have a break so I’m not sure when I am due. Usually If I missed 2-3 pills I would start bleeding but I haven't had any bleeding for 3 weeks. I took two clearblue tests and the results are two very thin blue lines. Not sure if it’s an evaporation lines or a positive result? I would post a picture but not sure how. Any advise would be appreciated? Thanks
