Conceive day before af?

[RubyMember]

I dtd the day before af came. Had a usual period. I then dtd several times during my usual fertile window although ovulation tests did not show I ovulated (day 12-15 only).

pregnancy test showed positive on day 28 of cycle when I was due on and got the line immediately.

Is it possible I conceived in previous cycle or just ovulation tests didn’t show?

Congratulations and my guess it the opks missed your peak

I would also think you just missed your peak. If your last period was normal it’s unlikely (although not impossible). Most people will get a clear positive on day 28 or when their period is due. But until you have a scan to date you won’t know for definite. You could try a digital test that shows weeks to see, but they’re not always that accurate.
