My breasts are sore and I'm having creamy white discharge

Need your help?!? So I want your thoughts. So I've done my best to calculate the possibility of being pregnant but I'm not too sure. My last period was towards the end of March (roughly the 25th/26th).. (I wasn't keeping track well..) I had unprotected sex using the pull out method twice in one night with my guy.. On April 5th (I think I ovulated around that time but unsure)... It didn't dawn on me for a few days that it was around ovulation time... That was the only time we've done it this month.. But I calculated when I should get my period for April and that should have been either a few days ago or now... Somewhere around this time. But I've had a few weird things and some not too weird... My boobs has been sore for a couple days now (they usually do get sore before my period but not this sore). I've had some discharge (creamy white) the last few days or so... I don't recall having that happen before any other period... I don't really feel cramps or back pain like I usually do at period time... I took a test yesterday morning and it was negative... I didn't do one today... I'm hoping Mother Nature drops on by... I'm giving it a few more days before I test again in hopes I'm losing my mind... (Ps I'm already a mommy to a 2 year old... But I just don't recall back to when I found out I was pregnant with my kiddo..) I don't want to mention anything to my guy yet unless I know for sure... Don't want to get hopes up...
