HELP ME PLEASE

Teresa

Hey girls, so I am currently 20 days late. I took 4 pregnancy tests an all came out positive! HOWEVER, I went to the clinic and got a vaginal ultrasound done and a urine test done, nothing was found and my tests were negative. My mind wasn’t at peace therefor took a 5th at home pregnancy test at home and CAME OUT POSITIVE! I went to a different clinic and they also took a urine test (week after last clinic visit) and it also came out negative. Ever happened to any of you guys!? I just want an answer and not even a Doctor can tell me.
