How long to wait before IVF?


Hi, my husband and I both turn 30 this year. We have been trying for a baby for 8 months with no luck. A few months back we decided to get tested to check everything is ok. My CD3 and CD21 blood tests and scans all came back normal. My husbands semen analysis came back normal (morphology was low at 3% but based on a count of 313m and concentration of 84%, the doctor said he was classified normal overall). For the last 8 months we've been taking pre conception supplements and I've been using OPKs to estimate ovulation timing. The doctor has also confirmed that I am ovulating. We are starting to ask ourselves when we would move to <a href="">IVF</a>/ICSI if we don't conceive naturally. We have decided that we would go private so that we have a bit more say over timings. We both feel ready for <a href="">IVF</a> now but think it would be sensible to give it a full 12 months to give us the best statistical chance of conceiving naturally. My question is, how long did you wait? Do you think that 12 months is long enough? Thanks!
