Hey guys! So I had sex about 2 months ago. Although it was protected, he kept messing with the condom because it kept coming off.  After that incident, I was 2 1/2 weeks late for my period. When I got my period, I was very relieved. However, my period lasted about 5 days instead of my normal 9-10. I read somewhere that what I was experiencing might have been implantation blood, that I wasnt really on my period.  A month passed. And now I'm on month 2. No period.  However, I'm experiencing signs of pregnancy such as:

Fatigue. missed period, headaches, back pain, cramping, white discharge, and now spotting. 

I just went to the restroom a few minutes ago and noticed some dark brown blood in my underwear (ew) But it was only a little bit, like 3 small spots. 

After I had sex the first time, I took a pregnancy test when I was 5 days late for my period and it came back negative. Is it possible that it was just too soon to take an actual test and that I'm pregnant now? I'd be around 7-8 weeks pregnant.
