Ovulation day and new symptoms: is it a sign!!

I am probably crazy lol but today is my ovulation day according to the app and today I’ve been sooo emotional, like cranky one minute then crying the next (I’m a mess) and it’s totally out of nowhere. We did the deed three days ago... could this be a sign something implanted? :o

I don’t ever usually feel this way when I ovulate except for the one time I got pregnant (resulted in a chemical pregnancy but still). Anyone else ever feel like this on their ovulation day before they got a BFP?

Or am I just finding signs out of nothing?
