Opinions please

So last month I had a suspected miscarriage I had a positive test on the 16th and by the 18th new tests were negative and I had the worst bedding going I only ever took that test as I felt sick and faint all the time and kept nearly passing out fast forward to now ive noticed my nipples are sensitive I’ve been craving the weirdest things like the smell of raw mince and the smell of chlorine and I have been super crankie took this test today and I think it broken the line in the middle isn’t a solid line it’s that normal obviously it’s negative so god knows why I’m so off
