Implantation dip advice

Lizz

Hello all! So I am currently 13dpo. Having some symptoms. Started testing at 10dpo but not positives just yet. Period if due in two day. I thought I had a implantation did on 8dpo but then I just had an even bigger dip this morning. I tested at 6:10 am like I do everyday but I did wake up around 3am and was back asleep by 3:30am. Did anyone else who is pregnant notice more then one dip during and after implantation? Baby dust to all!
