Could I be pregnant!? Help!

Chloe

I am 18 years old, my bf and I have been together for 4 years. We are sexually active. We had sex on Nov 2nd 2017 (our anniversary day). It was the day after my period ended. Period was Oct 26-Nov 1st. Normal period. We’ve had sex between then and now. Anyways, my period should have came around the 26th-27th of November and ended around Dec 1st -2nd. Today is Dec 4th. I figured ok well maybe it’s late. I have random late periods and won’t be pregnant. It’s just always kinda off a few days. But that would mean I’m about 9 days late. I’ve been moody, hungry, and peeing constantly(which I figured didnt happen till later in pregnancy) I’ve felt fatigue but cannot sleep. I had a milky white discharge for like 4 days straight, then it went away, and now I’ve been constipated. So, as any normal person I took a test. It appeared negative, but the supposed “2nd line” wasn’t really a line. More like a faded purple. I shrugged It off and read it as negative because truly it looked negative and my bf said it did too. Considering it wasn’t much of a 2nd line, just like purple fade from where the pee traveled up the pregnancy test. I Was it a messed up test? Defective test??

I want to get another test. Just to make sure. Has anyone experienced this and seemed that this test was positive??
