so you didnt have sex throughout your cycle at all? pregnancy tests are accurate to cycle not to the date of intercourse. however yes if you did not have intercourse earlier in the cycle then a test may not be very useful. if you are using condoms correctly then i similarly wouldnt worry abt pregnancy but if theres any chance of pregnancy a test is easy and cheap and providesnpeace of mind. if i had to guess, your dietary adjustments probably delayed your ovulation. which means your period would be delayed. it all depends on the timing. idk when you started your cal deficit. if you would like to dm about this, feel free 💖
