Period or implantation?

Tiffany

Hiya

I'm just looking for some general advice really I've been ttc for around 3 years I've been with my partner for almost 7 years was diagnosed with pcos last year after not having a period for 9 months nothing unusual, anyhow skip forward to this year my last proper period was the day after my birthday which was the 8th of April, Yesterday I woke and there was light blood when I wiped had a pad on thinking my period was here but I've had nothing since? Is this a period or implantation bleeding?

Sorry for the long post but I'm so confused by it all.
