Oh I really feel for you. I was stuck in the age/weight dilemma too. I was 38 when I had my TFMR and my rainbow baby is due on my 40th birthday!
I posted the below on another thread where we talked about what we were doing to boost our fertility. I truly believe the fertility lubricant really helped. I also really liked using the LH strips and doing temping to time everything correctly. It's a lot of info but hope it might give you some inspiration. I posted this on the 5th Feb and we got pregnant that month - our fourth cycle after the TFMR.
Vitamins everyday:
Ubiquinol 600mg & Omega 3, 6, 9 (Just over 2 months of taking this so far). (for egg quality)
Her9 pre/during/post natal multivitamin inc things like Omega 3, folate, choline, vit D, iron, zinc, selenium etc.
Prescribed 5mg folic acid as my BMI is over 30 and I'm 39.
Foods: Long term vegetarian, Mediterranean style diet, lots of wholegrains, vegetables, full fat Greek yogurt, nuts, chia, eggs, tofu, lentils and chickpeas. I still like crisps, wine gums, etc so not an angel but my meals are all nutritious. I'm also really into fermenting at the moment, making my own sauerkrauts etc. Good for the gut! I had just started making my own before the TFMR so I was glad to have them in my diet after the IV antibiotics I had in hospital.
Exercise: Dog walks, kettlebells once a week. Struggle to get many steps in at work and in the winter, could really be doing with doing more.
Other: Preseed. We used this for a few months before falling pregnant before and husband is convinced it helped. Have just ordered ConceivePlus for this month for a change to see if that helps.
Testing: Ovulation strips from day 10ish onwards until a peak is found. Now on third month of taking my BBT too.
We're trying to do the Sperm Meets Egg Plan too, although tend to start at day 10/11. Haven't managed the 'one for luck' at the end yet either as we always run out of steam. Will try this month.
I know I need to lose weight. It's sooooo hard. I've always been a 16 my whole life, and currently an 18. I've lost weight over the years, I was 4 st lighter at one point. Just find it so so hard now.
I also love wine and coffee! Since Christmas I've made a real effort to cut back, stopped drinking during the week. I have a proper coffee every morning and a couple of instant coffees throughout the day. When I was pregnant I cut out the instant and had a watered down proper coff.
