I'm 24 years old & my hubby & I have been TTC for almost 2 years now (after we had a miscarriage at 2months). My periods are always on time except for last month when I was 3days late, this month I'm 7days late and have never been this late before my breasts are acheing but don't have any other preg symptoms. I took a hpt (in the morning)on day 28 of my cycle and it came back negative, I have just taken another one now on day 35 but still clearly negative, now am very worried and wondering if my system is functioning properly or what? Should i go see my gyna today (on day 35) or will it be too early?? Plz help
