2 Miscarriages and now confused??

Natalie

So I had a miscarriage in August at 11 weeks, and a miscarriage in February at 6 weeks. Now I'm 3 days late and got a positive pregnancy test this AM via digital clear blue. I went to planned parenthood at 4:10pm today and got a negative test. She told me it could be to early and they're more accurate in the morning early on but I'm just so mixed with emotions..... I wanted to wait 8-12 months before getting pregnant a 3rd time because of my past with miscarriages but it happened now and I'm worried. Do you think I'm pregnant?
