I think this is a great example for ladies who are frustrated by their irregular cycles, and are worried it might mean they don't conceive right away. Sorry for the length, but I think it's reassuring!
A little background: I have been charting and obsessing over my cycle since my husband and I got married. In all honesty, I think it was detrimental to our sex life and added unnecessary stress to both of our lives. In order to keep up the data collection but not worry about it, we made a little Excel program that allowed each of us to alternate symptothermal inputs, but that wouldn't let us see the pattern until after the cycle completed. On our first month of "no-stress-conception" (which was, I must admit, a bit rabbit like -- woohoo! :P), and during a very weird cycle, bam -- BFP last week, at 18DPO. Four of them, actually. Haven't been to the doc yet (going in two days), but super upbeat and eager to start getting some real tests/scans!
My cycle was perhaps two short cycles, or one long cycle with breakthrough bleeding. I am leaning toward two short cycles: one 27-day anovulatory (no temp spikes/erratic) followed by a short, scant period; then, another where I seem to have ovulated on CD8, as after that day my temps spiked and stayed high for 18 days. I had a hunch (the DH even called it), but when no AF came, I knew I had to test. Of course, this could all change if it turns out that scant period was actually implantation bleeding when I get a fetal age, but I am skeptical, as I never spiked in temps afterward and actually had a BFN (took it just in case) about a week after the bleeding stopped.
Here are the symptoms I've had since that CD8 temp spike:
1DPO-7DPO: Nothing out of the ordinary.
8DPO: Revolted by the smell of peanut butter (which I normally love but now appears to, sadly, be one of my pregnancy aversions!).
9DPO-18DPO: VERY wet discharge, abnormal for me.
14DPO-18DPO: Nauseous/food aversion. Had to force myself to eat.
14DPO: Strong cramping, extremely irritable.
15DPO: Extremely irritable, VERY sore upper lady bits.
15DPO: Started strongly craving meat (and I'm a vegetarian!).
18DPO: One positive BFP! Booked a doctor's visit.
20DPO: Crazy nosebleed (also abnormal for me, as I've never had one in my life), second BFP!
Anyway, hopefully the doctor can shed some more light on what went on with me this go 'round, but there isn't a doubt in my mind that I'm preggers! Have had zero bleeding, just a bit crampy, nauseous, and emotionally insane since then.
I hope this information helps wannabe-moms that are nervous about their crazy, erratic cycles.
