Implantation?

Nicole • 2 👼🏼👼🏼, 🌈 on the way 1-6-20

Had this when I went pee this afternoon. I’m suppose to start AF the 28th. So I feel like it way to late for IB. but the other 2 times I got pregnant (both ended in MC)my ultrasound was always a week 1/2 sooner than what they thought so I ovulated way later than what they thought. What are your guys thoughts? I’ve never had this before a period
