Is It Implantation Bleeding ?

I have never had this before! On Monday I had a light pink discharge which is day 20 of my cycle and by the evening it was gone! The next day (day 21) I had so more pink spotting , this time a bit more stringy, calmed down the night but there was still pink blood when I wiped ! Then I had a spot of red blood the next day(day 22) that was it ! I went to the docs during the day . My pregnancy test was negative ! She said I had to come back on the 26 to test again.Nothing for the night! Then spotting again the next day (day 23 ) in the morning , just pinkish brown and I was at my friends house in the evening when I went to the bathroom and wiped it was dark red. The darkest I've ever seen blood come out of me ( sorry tmi ) . Then today(day 24) just light spotting again like it was finally going away, then just now it's brownish pink again. I know I have to wait for the 26th to test but we all know what the waiting game is like . So I was just wondering if any of you had any success stories after an experience similar to mine or just what you think generally .

Also my breast are tender and I'm bloated . I have have cramps that I can't even explain , they are mild or just medium sometimes

Please be nice 😊
