I'm 32 years old, been TTC for over two years now. Had a miscarriage last year, very early on. Have PCOS so ovulation is very hit and miss! Periods are regular. Cycle length is anything from 28-33 days. For the past 3/4 cycles it's been more 28. I'm on day 30 cycle now and AF hasn't arrived, I'm petrified to take a test incase of BFN. My breasts are very tender but I think I have period pain! I can't be sure if it's period pain or anxiety! Anyone else in a similar situ?
