Testing

Ok so here's what happened. Wonder if anyone else has had this happen... 
​Took 2 tests & both were positive. Went to prompt care where they did a urine test as well. Negative.... So then I was like okay well it was negative so I'm not. So I waited and waited and waited and no period. Then started spotting dark brown (sorry if TMI). So finally I was like I guess it's time to go see my doc. Took a urine test and doc came n and was like it was negative. Then moments later the nurse came in to get him. The test was positive now. So he was stumped. So they did my blood levels and my numbers were decreasing not increasing. Needless to say I misscarried but it was a weird situation!
