ADVICE NEEDED PLEASE

Katieann
My periods are irregular with my longest cycle being 36 days but for the past couple of months it's been pretty regular and my P.D. app is usually spot on about when I start my period. It said I was supposed to start the tenth which now would make me 11 days late but Glow said the 14th which would make me 7 days late while Ovia said the 15th and I'm now 4 days past my longest cycle. So besides it being late-I've begun to have sore nipples for the past week and tender breasts for the past couple of days. On 8-9 dpo I had watery spotting all throughout the day and for the past 4-5 days I've had white discharge. I've been nauseous on and off going from highs to lows. I also had pelvic and stomach cramps on and off for a week or so. I can also smell things very strongly. . . Which is weird for me because I have almost no sense of smell in general usually. But negative tests so far.
