Has anyone ever gotten negative pregnancy tests, but then later found out you are pregnant? My period is 4 days late, and I’ve taken 3 pregnancy tests. All different days of my cycle, not all in one day, but every one of them came up negative. I haven’t missed a period in over 2 years. I had irregular periods, but when I lost weight they became regular again. Any experience with this? I did have an endoscopy on May 21st, but my cycle was regular in June.
