Combined pill

Hello everyone, has anyone got pregnant after taking the combined pill.

So I was on the combined pill for a couple weeks and stopped to try for a baby on the 3rd jan. on the 7th I was spotting until the 15th weirdly started everyday at 5pm for an hour or so...

I have been on 3 kinds of contraception before so I have no idea on my period tracking.

So I classed the spotting as a period to get a rough idea when one should be due. This app predicted 4 days ago. I still haven’t come on.

Any suggestion on what to do next?

Thankyou.
