Help?? TMI

Ju

Okay so Im trying to conceive and my AF isnt due for 3 more days til the 20th

Did I just experience implantation bleeding? I went pee and had light pink spots. Been getting small cramps afterwards and this is what happened after about 20 mins. It just gushed kind of pretty much. Not getting any more cramps afterwards and not spotting or anything afterwards. Is this was implantation bleeding is????
