Nervous about my prenatal bloodwork results?

I got my prenatal bloodwork done on Monday. My obgyn has their own lab. Its now Thursday. I asked how long it usually takes to come back and she said 2-3 days. She said they wont call unless something is wrong. Today is the third day and no call yet but im still freaking out thinking something isnt right. Ive always had bad anxiety over HIV and stds due to my past mistakes, so im very nervous. If those tests came up positive would that delay the results and the call? I just want my mind at ease! Ive been praying and praying to God because all i want in life is a happy healthy family. Am i overreacting? Ive always been a bad hyperchondriac since i was little.
