Does anyone have pregnancy symptoms but negative tests? My period was a week late now some small amounts of brown blood with very little traces of pink for a couple days. I'm feeling full in my uterus like I was with my son and starving like before and gassy and chest is sore. Tests say negative but my body is going crazy. My period have been normal last three periods after we lost our son. Now this? Not sure what to think. Had anyone taken awhile for levels to show up. I was 2.5 months before we found out with our son.
