i took out my mirena on May 16th. on May 25th, i started my period. it lasted 2 days. June 24th i started my period. it lasted 3 days. July 24th started my period. it lasted 4 days. This month on August 14th, i got an LH surge on an ovulation kit. baby danced, used preseed. this is my first month using ovulation kit and preseed btw. Glow moved my period to August 29th. My period has always started on the same day every month since ive taken my mirena out. would you consider my period late? could i have ovulated late? could me ovulating late cause my period start day to change? ive taken a pregnancy test this morning but bfn :( just trying to understand it all. thanks.
