Is it too soon to test?

Sorry if this is a long rambling post but below is my calendar. I stopped taking my birth control a month ago and according to my cycle on birth control I should’ve ovulated on Dec 27th.

We had unprotected sex and he pulled out (not effective I know) on Jan 2nd. On the 1st and 2nd I was having clear stretchy discharge like if you were fertile. So I’m wondering if stopping my BC threw my cycle off.

As you can see from the photo I’m now 4 days late for my period but it’s only been 12 days since we had sex. Is it too soon to test and get an accurate result or how long should I wait?

I’m not even sure if I could be pregnant or if my cycle is just messed up from stopping BC but I’ve stopped it in the past and never had this issue.
