Hi everyone, I have a few worries that maybe someone has some insight on.
Here's some background info:
I am 20 years old, sexually active with my fiance and I haven't had my period since labor day weekend (Week of Sep. 4th). My periods are usually fairly regular, sometimes they're a week off, but nothing major.

Today is December 4th and I still haven't menstruated since then! The only thing I can really think of that I've done out of the ordinary is that I had a blood donation late september, and another one in late November. 8 weeks apart. Has anyone ever experienced missed periods because of this? I've been donating blood for 4-5 years but this is the first time I have this year. I've never missed a period in the past from donating blood that I can remember. I also have borderline anemia, so I'm not clinically considered anemic, but my levels are always very low.

I was worried I might be pregnant... even though I haven't had any unprotected sex. I might be a bit paranoid! I'm 99% sure I'm not pregnant, A) Because I've used a condom for any sexual activities with my long term partner and there's never been any condom breaks/incidents and I have no irregular pregnancy-like symptoms and B) I've taken 2 pregnancy tests (just to be sure!) once in october when the time I usually have my period came and went, and once again today and both were negative.

I have insurance, but i've never seen a ob/gyn as I am a bit nervous around doctors and a bit modest. This stems from some abuse as a teenager. So the doctor is really a last resort.
I'm a little worried I might have some hormonal/reproductive problems, and so I wanted so seek a second opinion before I make the jump and go see a gynecologist.

Thanks for your help everyone.

You should really go see a doctor. Donating blood shouldn't have any effect on your period.

You could still be pregnant even though the at home test said otherwise. There is such thing as a false negative.
