Firstly, sorry to everyone for my late reply! I may have asked questions below you've already answered during me typing this when I've had chance so please forgive that lol! I have a 7and a half year old with Autism and ADHD and today has been a rather heightened one! Just got the time to sit down now and read all of your replies. Happy to have you all here!
@ohsure, TTC since Jan '18. It took 18 months for my first but I had really irregular periods then. I use 4 apps currently, trying to work out which one I like best to stick with!
Fertility Friend
Flo
Glow
Ovia
I've just started temping the last month. Will be heading to the GP in January just for a check up to make sure I'm all in working order lol! x
Hi @Butterfliesandroses, welcome to the thread 
Congratulations on your promotion! I ordered some cheap OPK strips online as well, but personally found the temping the most reliable. I can never tell If the strips really are dark enough for a positive or not! x
Welcome @Outwards To the thread  good luck with your fertility tests! I'll be going down that path in January. I feel your pain with the TWW, for me, EVERYTHING becomes a possibly pregnancy sign! Keeping my fingers crossed for your January BFP x
Welcome @iano, ooh exciting! How long until AF is due? Keep us posted! It's so tough holding on to test isn't it? I always give in and test then tell myself maybe it's just BFN because I tested too early! Thinking of you and hoping you get your BFP!
I also really struggled with the abbreviations! I try to write them in full but always forget, the main ones I use are:
AF - aunt flow (period)
BFN / BFP - big fat negative / positive
DPO - Days past ovulation
CD - cycle day
This should help with the rest:

Welcome to the thread @ttc12019 we have the same length cycles! It can be a bit overwhelming. I've read Mumsnet for so long but only recently became active. There's a list above with what the abbreviations mean and always ask ask ask. We're all here to support each other x
Hi @Hannah192 welcome to the thread  Ooh exciting your first! Good luck on your journey. Have you spoke to GP about cycles coming back after stopping them? I've only had the DEPO injection, mine came back 2 months later? Keep us updated x
Welcome @EssJayyCee to the thread
are you going anywhere nice? I also suffered cysts and had irregular cycles. It took 18months for my first without any tracking or temping etc. Are you going be be temping from March? Your cycles might be irregular but hopefully (please someone correct me if I'm wrong) the temping will help you to track each one each month, with the rise in temp that stays up just before ovulation? I love that resolution about getting in better shape. Since my son 7 years ago I haven't looked after myself at all! I'm 6st heavier than back then! We're having a mad binge the last few days of this year, then starting in January making small but achievable goals to hit along the way! I'm so proud of you for taking the leap and getting yourself back on track. It can be a real struggle once we find ourselves in a cycle to break out of it and find time and energy for self care. I wish you all the best with your personal journey. Look forward to hearing from you again! x
Look forward to speaking more x
