Hi Kylie,
Welcome! Hope your ttc journey is short and sweet.
I can definitely relate to your story. I haven't shared this on OB before but I also suffered anorexia as a teenager and ever since, its been a real struggle to find a balance. While I am in a healthy place now, I still find my body is extremely sensitive to any changes - be it stress, exercise or illness - and as a result AF can disappear for any length of time without warning (and not for the reason I'd want!). Knowing this, DH and I decided to stop using contraception when we got married in 2008. This last year we've really stepped up our efforts and through a combination of acupuncture, seeing a naturopath and taking clomid (which has had the biggest effect), I finally have a "normal" cycle. We're still patiently waiting for our BFP but I feel like its possible now!
Sorry for rambling about my story! I hope I haven't scared you - I'm not necessarily the norm and there's a good chance your BFP is just around the corner. However, I would advise getting a bit of help - have a chat to your gp or try out a naturopath. If you're like me, you're probably a bit deficient in some areas, and the naturopath will help sort out what you need for general health as well as ttc (I'm sure they can help with your skin probs too). They will probably get you charting and you will learn a lot about your cycle and body - so I believe its a good investment!
Finally, I just want to say its really great to hear you feel you've regained control over your eating and lifestyle. I know this is something that never really leaves you and its an ongoing battle - but it sounds like you're definitely on the right track.
If you ever want to chat about anything - feel free to pm me
Take care xx
