AF due 10/2. cramping last 2 weeks.

Is this a good sign? i have read of people having the same symptoms and getting their BFP! hope thats the case for me. I felt like i was on my period last week a few days and now i have had mild cramping. i am 8 dpo. i also almost gagged when i took my prenatal chewy vitamin the other day and have had some weird scents. send me all the baby dust you can please!
