Am I doing everything I can?

Km
Weve been ttc for 3 months now. I take prenatals, maca power, eat well and work out. We have sex every other day and every day during fertile times. It's getting very frustrating knowing everyone else is getting BFPs and don't even plan and were devasted each month when AF comes. Any advice? I know it can take while but this stress and frusteration is killing me :(
