It really depends on how long your LP is. If you normally only have a 10-12 day lp, then yes it can. Implantation generally happens between 7-11dpo(6 and 12 happen but are the more rare) and IB can happen anywhere from day of to two days after.
This is why some women mistake IB for a light period. It does sometimes happen if you have slightly heavy IB instead of just a few drops.
If you suspect IB instead of af then test.
