my walmart brand .88 c test was negative and stayed negative WITHIN the time frame, the next day i pull the test out of my drawer and it was literally POSITIVE!!! i took two more tests that were negative and stayed negative, i never went back to look at those two, i ended up getting my NORMAL period as <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> predicted, the sex was protected and i wasn’t ovulating. can someone give me peace of mind ?? the last time i had sex was in december...the test mishap just has me all shooken up.. BTW NO I AM NOT TTC!!!!
