strange symptoms why?

hey guys, so the past few months I have had a very specific set of symptoms leading up to ovulation and specific symptoms after ovulation leading up to my period but this month my symptoms are all wacky and I was hoping someone could help me understand why!

really quick, here is a little background on my situation....I got off my BC pill in July 2017 (last year) but it took 9 months, until April 2018, for my body to actually start ovulating. So for the past 4 months (since April) I have had exactly 28 day cycles always ovulating on day 15 or 16 and my period is always 5 days long

Well, all of my cycles since April have had the same set of symptoms. My period is medium flow, lasts 5 days, cramping for the first 3 days. Creamy CM starts around CD 8. Then around CD 10 my breasts get a little tender and my CM gets super heavy. Around CD 13 I get EWCM and my beats become painfully tender (especially my right one). ovulate CD 15 or CD 16. Then my breasts stay painfully tender until my period begins. My EWCM turns creamy around CD 22 and stays heavy until my period starts. Then around CD 25

I start cramping and my period starts on CD 28.

This cycle that I'm currently on is WEIRD though. no sore brests at all, I only had EWCM on CD 15 and CD 16. I did ovulate on CD 15 based on my OPKs. I wasnt able to have sex before or on my ovulation day because my husband was away for work but we did have sex the day after I ovulated so I know my chances of getting pregnant are low but still possible (yes we are TTC)! i am also having really bad cramps and mild nausea which is unusual for this time on my cycle I am only 5 DPO today (CD 20). so obviously It's too early to know if I'm pregnant but I'm just so confused!

can anyone shed a little light on my symptoms?
