For your period...?
Was due on over the weekend, thought it was annoying timing because i was going to be seeing dp (LDR, seem to have had about 1000 periods since we gor together 6 months ago...😒) so was glad when it never showed up.
No on day 31 of a normally 28/29 day cycle, longest its been in the last 6 months is 30 days.
I have a copper coil so i would have thought the chances of falling pregnant are pretty slim?
How long would you leave it before getting concerned?
