Could I be pregnant

Theresa
Okay so this month I had sex five days before my period. My period showed up on the 8th went off on the 10th showed back up on the 11th and has been gone since ... So me and my husband have been bd'ng like there is no tomorrow... And about 6days ago I experienced some light cramping and light pink and brown tinged diacharge which I was told I started ovulating early.... So I started ovulating on the 12th and me and hubby bd last night and all last week and I woke up to real light pink spotting this morning.... I want to know what anyone thinks of my story and if I could have possibly be experiencing implantation bleeding this morning!!! Ttc for baby 3
