12dpo

I’m 12 dpo today and had BFN @ 11 and 10dpo. I had what I’m think was implantation bleeding @ 8dpo. I wiped twice and it was really really light pink, haven’t had anymore since. Ever since I have had some pulling/pinching cramps. Is this a good sign of pregnancy? I don’t have any other symptoms other than my breasts normally hurt before my period and they don’t this time and I normally want sweets before my period but this time I can’t get enough salt. Fingers crossed 🤞🏻
