Sneak peek

Anyone else take the sneak peek gender test ? I took the test last week thinking that i was about 8-9 weeks along due to the fact i was not able to see when was my exact day for my last period in my phone because the screen went completely black I was in the process of waiting on a new one to be shipped to me. Anyways i did the test before i was able to see my exact lmp. I sent it off got the results which was a boy hoping for sneak

Peek to be wrong lol. Well i just got my phone today and app says I’m just hitting 8 weeks

As of yesterday. I’m wondering maybe if I’ve done

The test to early and got a boy result or if it’s possibly contaminated. Or could it be a possibility that I could have my boyfriends DNA in my blood because we had sex the night before?
