How much is too much?

Little Tog
Hi everyone, newbie to Glow here ☺️ Trying for #3 (with different partner to the first two) and 10 years since last pregnancy!! Second month of trying and got my AF yesterday 😢 - it still feels as hard to get pregnant as it did first time round. Is there such a thing as trying too hard? We BD every other day? Have just ordered pre seed and Geritol to see if this helps?
