So I am 7dpo right now, AF due in one week... right smack in the middle of my two week wait and my boobs are sore, I have a medium amount of sudden thinner almost watery discharge, and I have had this sharp twinging occasional pain deep in my lower abdomen that isn’t bad pain but just weird. I have had a little bit of dull period like cramps too. Could this be implantation or something else? I don’t usually get any PMS symptoms this early so I’m confused.
