What shall I do?

Stupid question alert... So I was supposed to (or did) ovulate on 28th April.

I tested at 10 and 12 dpo and was negative.

I'm now 5 days late.

However I did have egg white cm on the day my period was due.

Does this mean I ovulated late or can you have ewcm while preggo?

Should I test again and put myself through that (bearing in mind it was - ve at 12dpo) or just suppose that I didn't ovulate...

How likely is it that a - ve test at 12dpo would now be positive?

Is that likely? With my first I had a reasonably strong positive at 13dpo.

Thanks a million
