Hormonal imbalance

I’m now 3 days late...I took a test on the day of my expected period and BFN. My boobs hurt, I have had a lot of discharge for about a week and I feel slightly queasy although I’ve had this before and not been pregnant. I’m holding off on testing to see if AF turns up soon...but I’m starting to worry that there is something going on with my hormones and that it is going to stop me conceiving. I used to be so regular but ever since I started trying my cycle has been unpredictable and my flow soooo much lighter. I’ve also had weight loss, pains in my ovaries and some mid cycle spotting including once after sex..anybody had similar experience? X
