I think I'm pregnant

So I've been waiting on my period, I've been having all the typical pre-period symptoms I normally have....but still no period. So I decided to just take a test this morning.....well 1 line popped up fast, but on the opposite side as the pic on the box says it should be on if it's Negative. Then a super faint 2nd line appeared.... I wasn't planning on getting pregnant right this second because my family and I are taking a trip to Europe in 4 weeks, which means I'd be in the throws of 1st trimester sickness. With my first pregnancy I felt horrible all day and night until about week 15/16! I'm terrified. 😩
