Step I markers for hep window period

[MudPhud20XX]

so FA says Anti-HBc and Anti-HBe are two markers for window period for hepatitis. It does say Anti-HBc is IgM, but does say the same for Anti-HBe. Anti-HBe should also be IgM since windoe peirod is still considered as acute (less than 6 months), or will it be the mixture of IgM or IgG? Many thanks in advance.

IgM shows up at 3 days, peaks at 2 weeks, disappears at 2 months
IgG shows up at 3 days, peaks at 5 years, disappears at 10 years

So..if it is greater than 2 months (but less than 6 months), it would be IgG
