Bitty (Like little blood bits), mucus discharge from Lady parts!

Hey! I signed up specifically to ask this I hope Im doing this right. I recently (Last Saturday, 25.07.2015) had a odd occurrence in my panties. I had a light discharge almost like a usual cleaning/ovulation discharge that our Lady bits do. But this time, what was different, is that I had little red bits come out which gave my discharge a red twinge.

Now googleing up this oddness had given me nothing but shock and fear. I have read dozen of articles on Implantation (Pregnancy) spotting and cancer. But my fellow female pal told me its probably just a UTI. Yet, I dont experience any burning pain. Like. The discharge was orderless. Im just thinknig the worst. As always. Haha!

What could this be? Is it just one of those things? Nothing I should worry about? If I still feel nervous by Friday, I will plan to go to the doctors. 

I have been fine since. Other symptoms I have been feeling;

- hadnt poop'd since Friday (But I managed to poop alittle bit today! Hoozah!)

-Well my stomach has gone quite podgy.

-My tummy (Below to the mid of my belly button) has been swirling all day.

Other things you should know;

-I have not had intercourse in three years. Yet my Boyfriend (Of two years, We wont have intercourse until one of us is protected. I plan on getting the implant.) Have been fooling around with the usual silly stuff. Likely hood of his semen reaching my bits are close to zero.

-I did go out drinking the night before. Not heavy drinking. 3 shots at the most.

-My boyfriend had a heavy heated session on the night of drinking and the morning after. The most he got to touching me was myself grinding upon his leg while I gave a 'handie'.

-Discharge was oderless. Just abit odd.

-Was only one little usual vaginal clean dollop of mucas. Hasnt happened since.

-Period isnt until around the 11th of May now. My last period was on the 12th of April.
