Delayed but No Signs of Pregnancy

Hello po mommies, is it possible na merong no signs of pregnancy? Exactly 1yr na this Feb since nakunan aq in my first pregnancy and no signs din noon yung naramdaman ko except continuous yng spotting ko kaya ko nalaman na preggy aq. Nakaabot pq ng 6weeks pero anembryonic pregnancy din yng ngyari sa akin. I've been hoping and praying for my rainbow baby ever since. Thanks po sa sasagot. God bless.
