Where should I post?/ Pink

Rachael
I'm not trying to post on the wrong page, but I have no idea where to post this that would be "politically correct" 
I got out of a relationship a few months ago where we were TTC so I obviously went off of my depo shot for that. It's been about nine months since I got off of it and my periods, although spacing goes from between 28-33 days, has been mostly regular when it starts. My flow is Medium first day, Heavy the second, and Light the third. Sometimes I spot on the fourth day. 
Anyway, I started seeing someone new about a month ago after being single for two months. I have yet to go back in birth control due to insurance switches at the new year. However, we are in no way TTC. 
We use condoms, but sometimes, (TMI) I have him go halfway through without one because I like the feel of it, and then pull out and use a condom before he ejaculates. However we usually go multiple rounds and I know Precum can carry sperm. But he pees between rounds almost every time, as far as I've noted. 
I'm 21 and however babycrazy I have been the last two years, I know this guy is not at all looking for that and I would never want my child born into a world where he (or she) could ever feel unwanted. 
Back to my point, well it had been 39 days and I finally thought  my period had started. But it's only light light spotting. Like pink when I wipe spotting. And it's been over a full week of that now with no heavy flow or any (idk how to word this) "egg or lining" coming out. Like I don't even need to use a tampon or anything. The official day count is ten days of "pink". My current SO and I are very sexually actively so I am kind of freaking out about possibly being pregnant. 
Three days ago I took an OTC test (dollar store. I'm a college student after all. haha) and it said negative. But I still haven't discharged anything substantial. And it's been over a week of just pink.
I HAVE been super stressed due to bills and switching my major twice last week, but wouldn't that just bring out my period early? Or just late? Not this middle ground of "pink"?
I'm honestly freaking out at this point and I don't know if it's from happiness at the possibility or fear from my SO's reaction. Besides this is probably all for nothing because that test said negative. 
If anyone has any advice on this, or even better, if you can recommend the best room to post this on, I'd really appreciate it. My mind is going a mile a minute. 
Thank you all so much for reading this little novella I've written. Hahaha.
