Anyone else?

I miscarried on April 15th and since then I can't help but be filled with thoughts of what I did wrong to lose this pregnancy. If it isn't what I did wrong it's what I did different to get pregnant. I had an ectopic pregnancy in March of 2018 and it took 16 cycles to get pregnant again. I hope and pray it does not take that long this time around. I have a wonderful ob and I have a follow up appointment with her in the 7th to see what my next steps are on my ttc journey. I have been taking metformin for 3 months and on a fertility diet my dr suggested. I think that contributed to me getting pregnant last cycle. I started using opks to track when my first period after the miscarriage will be and surprisingly got a positive exactly two weeks after the bleeding stopped. I did bd three times in my fertile window so maybe it will happen again quickly.
