Started pill 17th December.Took it for 5 days then decided another baby so stopped. Had a bleed then had sex days after,chance of pregnancy?

I started the pill in December on the 17th.. I only took it until the 22nd then stopped as we decided to have another baby straight away, I then began a bleed, not sure if it was my actual period as you bleed from taking pill but from the 23rd until the 28th. Once I had finished my bleed or period d We had unprotected sex on the 31st December and today twice (the 4th January). Will I have been ovulating when I had sex or is there a high chance I could get pregnant? Just with me taking the pill then stopping I’m unsure and we really want another one thanks!
