Hi PrincessVicky,
I may not be of much help, but here's my problem! Might save you troubles, don't know but here goes....
Spend what felt like a lifetime having weird periods, super duper long cycles. Saying that I knew that conceiving was going to be a major problem, since all the tricks in the books are for someone on regular 28 days cycle, so duh!
But nevertheless, I tried this method found here: en.wikipedia.org/wiki/Basal_body_temperature.
Followed this, took me a year, getting off PILL in August, waiting for infection, from PILL, to clear up, did basal body charting thing, and following August was pregnant.
Second one, was spur-of-the-moment, and here's the part, since iron-levels were better, I asked hubby if he wanted a son now, he said yes and voila I'm throwing up again.
Long story short, for you do the pills if you want, that's entirely up to you. Me, I would go get a blood test to find out your storage/levels of iron. That was (and still is) my lifelong problem, iron-deficiency, nearly no storage of iron, permanently anemic.
As a bit of personal knowledge, doctors do not do this test automatically, shame as it help me and countless women!
Hope it's useful to you, good luck, you have every rights in the world to want to be pregnant. Just don't shoot the messenger - SMILE! Later CD
