Implantation bleeding

So 9 or 10dpo was yesterday and I was suffering with hectic nausea and dizziness. Then trying to sleep I found I was cramping and had bad back pain also. Have been having vivid dreams since 6 or 7dpo, one I was using a contraction timing app and was in labour and the other I had a baby on a bus. Now today at 10 or 11dpo I have had mild nausea, insomnia (trouble falling to sleep and awake at 4:30 very unlike me. I've been cramping like AF since this morning and had light pink smearing when I wiped but only once. Since then I keep thinking I've gotten it but its just really heavy creamy discharge. Just wondering if anyone had similar experiences and went on to have a BFP
