Am I pregnant or not ?

I didn’t get my period January the day I was expected too. Which I’m always accurate. I had unprotected sex. I took a pregnancy test and had a faded line you can barely see but it looked like as if it was going to form but didn’t. I took another one and it came out negative. Idk if I’m taking the test to early and should give it time? What should I do wait a little longer and take another one in a week or two? idk.
