Please I need an opinion

1st a little background about myself...I’m 46 years old. Been TTC for over a year. Had 2 miscarriages in the last year. Both pregnancies happened naturally. I don’t have any previous children. In the last 2 months, i had two failed IUIs. Which was very physically and emotionally devastating on me. The last time my RE kinda suggested we go for something more aggressive like IVF. Since IVF is more extensive treatment and requires much more medication, I want to give my body some rest and take care of myself by taking vitamins like co q 10, dhea...and just overall heal myself before starting such treatment. My husband and I also planing a trip overseas in May so I want to enjoy our trip. But here is thing..I’m diagnosed with diminished ovarian reserve so I’m really worried that waiting 2-3 month will completely ruin the small chance that I do have. My instinct is telling me to take a break but I don’t know if in this situation I trust my instinct. I want to hear from everyone..what would you do if you were in my shoes? Sorry for the long post and thank you for reading it.
