New to TTC

Hey ladies. so this is month #1 of TTC. the first letdown his upon us. We have been throwing astound ideas of how to promote conception. I have slightly irregular periods. For example, this month af started 5 days early and I was shooting pink and brown for 2 days. I thought it was IB, but it was that bitch Aunt Flow hitting me with reality. Do you recommend opks? BDing every other day is not an option as our work schedules are crazy. I heard BBT isn't a true sign of ovulation either. Any advice would be so much appreciated. We had a MC 1 year ago and it took us a year to heal emotionally.
