My boobs once in a while will get sore 2 days before AF

This time right after ovulation they have felt full super nice and luscious. They feel round and heavy my nipples also look bigger. It’s lasted like two weeks

Here’s the thing I ovulate on cd13 (confirm by temping) I have 31 day cycles my luteal phase is sooo long 14 days + as of now I’m 11dpo and my period isn’t due until June 22nd.

Is that a good enough symptom to test early?

Unfortunately I only have a gold frer digital it says it works 6 days earlier but it’s a digital I heard they need more hcg

Oh and my boobs are itchy AF
