Started bleeding again 3 weeks after Chemical PG

[Tamashii]

I had a chemical PG followed by passing all the clotting with no pain followed by bleeding for 2 weeks. This all stopped last Saturday but today I noticed bright red bleeding again and AF like cramping. It hasn't come to anything but it is not time for next AF. This is not due until 6 Sept ish...

Is this normal after chemical PG?

Any advice would be great thanks
