This is going to get a little confusing but I'm going to go ahead and tell you all anyway...
I'm a horrible tracker of my period and all but luckily I have a wonderful app on my phone that lets me know when my period is due & when I am ovulating.. (M Cycles if you're wondering).. It's been surprisingly RIGHT ON... Until now. My last period started October 17th (when I started spotting) and then it was a full on period by October 19th. According to the app, my period was due November 14th.. I am officially 11 days past my due period. I was so sure I was pregnant until I took 3 pregnancy tests (at 3 days late, 5 days late & 9 days late) and all 3 said negative. Today (November 25th), I started having some brownish spotting (but no blood or anything like that) and only when I wipe after using the restroom.
Slight cramps (mostly in my right ovary) but no real period. I have noticed that I'm urinating more than usual (I hate public restrooms and got to where I have been okay not using the restroom at work..but now I am pretty much being forced to use the restroom at work)...
I generally am a pretty tired person but lately I am just exhausted at night after work (I'm an even coordinator but on weekdays I literally sit at a desk all day... nothing exhausting about it)...
I haven't been anymore stressed than usual or anything. I've actually been happier than ever lately... has anyone else had this problem or know what the problem might be? Has anyone had these things happen and had a positive turn out? I have an almost 6 year old daughter and I'd love to give her a sibling. My boyfriend and I have been together for 5 years and he's being very supportive of the situation, even though we're both pretty confused at the signs....
I apologize if I posted this in the wrong area or board or whatever. I'm new to this and I just wanted some advice. Thank you for ANY/ALL replies

Re: Could I possibly be pregnant?
I would recommend you start charting for real - meaning, start charting your BBT. There's no way to confirm your period is "late " if you don't know when you ovulate. There's no way to know when/if you ovulate if you don't temp.
I HIGHLY recommend that you go to the Trying To Get Pregnant board and read the newbie blog.

Actually the pee tests at the doctors are sometimes less sensitive than the ones over the counter.
You included the dates of your last period in your OP, but that information is fairly irrelevant to predicting when your next period will be and whether or not your late. What day did you ovulate? That would be more helpful. Because to me it sounds like you ovulated late and you're about to start your period.
Please don't waste a doctors appointment until you go 60 days without a period. If the HPT is negative, then you're not pregnant at this time.
And I'm not sure what information you think we would have the the HPT would not have already told you.

@brittney, wow, I am appalled at the responses you got from those horrible ladies. All you ladies are rude and lack any empathy or humanity. I seriously feel sorry for your kids for those of you who claim to be mothers.
If you want to know with absolute certainty, go to the doc. I am not sure if these ladies work for Obama or something and don't want you going to the doc out of fear of increasing their health premiums, but screw them. Do as you feel. Good luck!
How original. And loe! I've seen the error of my ways! Please. This is clearly not the site for you. There are plenty of glitter and rainbow forums that you'll be able to just make yourself right at home. Buy bye.
