7 negatives-no symptoms- but just "feel" pregnant-Help pls? - bloody mucus two days period expected

During these days, I have 7 tests were all negative and all taken in just 3.5 months (approximately the first 5 weeks and last Thursday, and 16 weeks) ... I used to meet every first and sky blue
All were negative. You have chest pain, nausea, no fatigue, no additional gas, not to urinate frequently.
However, I gained 10 pounds in 2 months and a certain "sense of movement in my stomach ... I'm not sure that motion is the gas or cramps.

To me nuts and I'm paranoid because my friend and I had unprotected sex for a few days after my period, but made sure not to come in me (Yeah, I know that before too *** contains sperm)
Anyway, I want a blood test and try it tomorrow ..

But someone had a similar history, being pregnant, was based on a "feeling"? Is that what I read soooo much about the pregnancy that I was every little movement, attributed to the fetal circulation? ..

Also my first period after unprotected sexual intercourse, "said episode was a bit strange ... as in the first buffer is full, and what looked like slime, but it seemed a little bloody mucus, accompanied by the stamp. after a first buffer, while others are never completely filled ... and lasted for about 2-3 days ..

may have been implantation bleeding? approximately 25 days after the announcement that the sex? as if it were implantation bleeding, it takes a lot of mucus or WTV was that?

I had my "period" in the settlement for another two months, much lighter than usual (without mucus or tissue, or has been, however, WTV)

All answers are welcome
