Girls, they were supposed to start their period on September 6th, but we left for Turkey a week before that, and I always have a delay when there's a change in climate. But after arriving, I took a test just in case, it was negative about two or three days ago. Yesterday I felt sick, drank NyQuil once. Today I decided to take another test, positive ? Of course, I wanted two lines and very happy about it, but I also got sick and took NyQuil. Now I'm scared ?+feeding. It doesn't seem real?
