Help!

Hello im a bit confused and scared as to whats going on :/ me and my husband are trying for a baby. Last 2 weeks I ovulated and I took two pregnancy test yesterday both came out positive. I have sore breast and mild cramping in between...today I took another test this morning and got another positive but a couple hours later I went to the restroom and when I wiped I had light pinkish blood with some mucus. I'm wondering if this is implantation bleeding or my period ?
