37 ... ttc for baby 2

Sa

I had had long previous ttc failed <a href="https://glowing.com/glow-fertility-program">iui</a> an anembryonic pregnancy and <a href="https://glowing.com/glow-fertility-program">ivf</a> transfer finally gave us our dream baby. Why i couldn'tconceive naturally remained unexplained as all the parameters used to come normal range. Failed second transfer for baby #2. Now ttc naturally but see no end to this. Got my first period 6mpp but my cycles have been irregular (though intermittent bleeding between cycles which also remained unexplained stopped after birth). I feel <a href="https://glowing.com/glow-fertility-program">ivf</a> will be the only route but i dont want to go. Any ttc tips / advise please?
