I need some advice please

Hello everyone! I got my first positive 5 days ago(9DPO) and they have been a fit darker everyday it seems like to me. On Saturday I had some very light spotting for about an hour. Yesterday I had some more for a short period of time and now today I’m spotting AGAIN! My app says I ovulated 7/2 and my period is supposed to start 7/16 but since I have gotten numerous positives, it’s not supposed to show up. Implantation would’ve already happened and I haven’t been been having any sex the last few days because during my first pregnancy it caused me to spot. I got my bloodwork done today and I’m supposed to schedule an appointment for an ultrasound tomorrow. Someone please help!
