With my second, I used EPT pregnancy tests, they never read my pregnancy. I had an extra test left over and just for fin took it at like 4 1/2 mos prego and it was false. I'm pregnant now with number three and tested positive the day after my period was epected with the clear blue easy digital test
It's never happen too me, I'm pregnant with my first...but it may come up negative if your hcg hormones are low. Try and retest again in a week
