Hello ladies. Is it true that if your hcg is really high sometimes a home pregnancy test won’t register it anymore? I’m currently 19 days late on my period had 3 positives in the time of June 30th-July 2nd & than started testing negative on home tests went to my primary doctor yesterday & they did a urine test but it came back negative so she sent me in for blood work & I now have to wait 3-5days some people told me it could have been a chemical but if it were a chemical shouldn’t i have been gotten my period by now? Help ladies thank you😊
