I'm sorry for your loss.
Last month was my first month charting too, and I was going out of my mind too every night I was having trouble sleeping, anticipating temping in the morning and hoping for my temp to stay up. I don't think I had a good night of sleep my whole 2WW!
Then I got AF today, which would've been 12dpo, so instead CD1, making this my shortest cycle ever! Ugh!!
Anyway, no real advice, just commiserating. I'm going to give it one more month, but if charting disrupts my life as much this coming month as it has the past two weeks, I'm done with it! I got pregnant with DS in 3 months without charting; this is now month 6 of TFAS, and the second month charting. It isn't the charting that causes the pregnancy!!
