Don't know where to post this 🤔

my period has been regular, for the most part, but for the first time EVER out of 9 years of bleeding, I was two months late, took a bunch of pregnancy tests all were negative, besides a blue dye and everyone said "it was most likely evp line" ..... flash forward two months later, and I've had a period the last two months (Guess their making up for the two months I was late??) but now my charts seem off, as if I'm bleeding twice a month now and ovulating twice a month also...... Can anyone help me on this? my charts are pretty accurate with everything, I go on the 26th to see a fertility doctor (we are TTC for almost a year now) so I plan on asking her. I'm just curious as to if this has happened to anyone else or do my charts look normal? my last period was March 21st, then I missed my period for 74 days (April-May), finally got my period on June 4th. 🤔🤔🤔🤔🤔🤔🤔
