Pregnant? Egg implantation ???

Alondra • I`ve been trying to get pregnant for 3 years if not more.A month ago I had a small miscarriage after my 6th week. I am now starting over and keeping my head up.
I've been having all day low abdomen cramps and sudden small pokes inside my vagina... for more than a week what could this be? It started after my period and my fertile window just closed recently... anyone? I've been ttc for 3 years for baby #1 so I'm waiting for af to not show but these cramps are annoying
