Trying to Conceive

Brenda :-):-):-)

Hello

I stopped using the pill about 3 days ago because we decided after 7 years we want to have a baby.

I had my last period 25-30 December 2018

We had sex the whole week and on this beautiful Sunday morning I woke up and had my period.

Is it implantation bleeding or actually my period because I left the pill.

I need help please.
