Getting depressed

First time posting. Been reading everyone’s posts trying to feel some comfort. TTC second baby. Daughter is 12yo. Last November we got pregnant after trying two months. Lost that baby at 3 months. Devastated. Been ttc since then...approx 6-7 months. I’m getting worried because it’s never taken me this long plus I’m 37yo and I know time is not on my side. Always have had ridiculously regular cycle and according to opk tests my ovulation has been consistent. I think it’s time to consider other fertility options. Hubby doesn’t think we need to. But im so depressed. I want that BFP so bad!!!
