I only ovulated three days ago based on positive opks and cm/cervix checks. But for the passed two days now my nipples have been really tender to the touch... I thought it would be too soon for symptoms like this and af isn't due until the 23rd which would be 10 days after ovulation. But I have never had any tenderness or soreness with my breasts or nipples around my period (or at all really) so I'm just wanting opinions on what could be the cause of this - I got this message on my other app that I use with this one.
