Implantation bleeding

HELP!!! So I had a super weird period. First, I was 2 days late.. then I rarely cramp, this time I had bad cramps, period was moderate but very short. Started Monday morning and didn't get moderate until late that same night. Then, it was light Tuesday until the evening. Yesterday there was only light pink blood when I wiped. Has anyone ever had this, and ended up being pregnant? I want to be pregnant so bad and I've been trying so hard. I've been having a few symptoms as well, but most noticeably was frequent urination.
