scared!! please help

Molly
So I'm 6 days late now and have taken 3 negative tests. Me and my boyfriend always use protection and always pull out and do the water test after. This months around ovulation time I experienced like a drop of pinkish blood and thought I was spotting. This is not normal for me to spot. It's normal for me to be a couple days late! For the past two days I have been feeling like I'm literally on my period but still no blood! I'm very confused and don't know what's going on. I'm 19 and am about a month from going to college 5 hours from home. I'm in no way ready for a baby and I tried to take all the right precautions 😭 someone please put my heart a ease.
