Help. Feeling discouraged.


My period is 3 days late. I have very regular periods, my cycles usually range from 30 to 34 days and I’m currently on what would be 36. I’ve taken four tests and all appear to be negative. I’ve had mild cramping for 4 days but nothing like I usually have. My boobs typically hurt very badly before my period starts and I have only had slight pains randomly but my nipples are very sensitive which is not normal for me. Thoughts? Could I be pregnant and it’s just too early to tell? This is our 7th month trying and I was on the pill for 15 years until I stopped taking it in June. My periods resumed right away and have been regular until now.
