I went out and had fun Friday the 17th and Saturday morning the 18th I was at work feeling nausea so I decided to take a test and it came back positive but the line was kinda light. My cycle was due on the 21st so Sunday morning I took 2 more and they was positive but the second lines on both was real light pink. So today I took a test it’s 01/20/20 and it was positive. This morning I think I started my PERIOD but wasn’t sure so I took another test and it took bout 3 minutes to show the second line but was positive. I went to the doctor and they did a urine test but it was negative and Told me it might be my cycle but I can wait it out and see but I’m confused on why was the test positive but negative a the clinic
