Hi, I'm 17 and my boyfriend of almost a year and I have been sexually active for most of our relationship. My periods are not usually regular, theyre always a few days late or early so I don't usually stress about it. It's even normal for them to be two weeks late when I have sex for the first time in a while.

From about august through November 2016, my periods were regularly cycling at one and a half months (So if it started on august 10 my next period would be on September 24) between the first starting day of my periods. Like I said this was the regular for three months. My last period, although, was on November 8th so I expected my next one to start on December 22nd-ish. When it didn't come that day, I told myself I would wait another two weeks until I would take a pregnancy test ( so January 8th 2017) because that would mark two months from my last period and I figured that would be way too long for a late period to show. Jan 8th passed this Sunday and at first I thought I got my period on that exact day but it's a really dark brown discharge that is thick but definitely not in the regular quantity of an actual period that I'm scaring myself into believing is implantation spotting because my boyfriend and I last had sex on January 3rd and this dark spotting is still continuing From the 8th to today (four days later) . 

We use condoms every single time, check for breakage, I watch to make sure it doesn't slip, and he always washes hands after anything. I am not on any kind of birth control besides condom use. I have not yet taken a pregnancy test out of fear but I am going to planned parenthood this weekend to get tested and work out birth control with a doctor.

I have been stressed a little lately because of the holidays and my senior year in general, as well as the thought of being pregnant. Could anyone please give me some insight if i could be pregnant and also how to talk about this with parents? Thank you.
