Hello! I'm very sorry for your loss, HELLP is such a devestating disease. I didn't encounter any issues ttc after HELLP but it was 14 months after the fact, it took two weeks and my family is known to be 'fertile murtles'. I read a book called 'Taking Charge of Your Fertility' before we concieved dd#1. Sounds like your already familiar w charting. Hmm...but I recall reading something like it's not a problem til you've been ttc for a year plus w no results. Best of luck to you ttc and have fun!
Maybe others will have better feedback! Take care!
