When we realised last week that we might be able to have a baby 'the old fashioned way' I immediately went to the app store and looked for an app to tell me about my cycle. I have an admission, that the two years that we were trying, I never charted. I knew how long my cycle was, and we worked with that. In fact, the month that I finally bought the basal body thermometer, was the month the ectopic pregnancy occurred.
So, I have my app, which is pretty cool, and by putting the dates it it has told me that since my ectopic, I have shifted to a 30-31 day cycle. I am aware I could have calculated this myself, but as we weren't ttc the last year while waiting for enough money for treatments, I never really bothered. It also tells me that this week is the week, and that I ovulate on Friday. I know I should back this up with charting but I'm really not very good at remembering to take my temperature. I have managed it three times over the last week and forgot to write it down once, as I tend to take it half asleep when the cat first jumps on me, then check it later when I feel more awake. I suck at charting.
As we have no idea whether we can conceive 'naturally,' and we have been strongly advised not to wait long at all before pursuing treatment, I don't feel too bad about my lack of initiative. If it's going to happen this way, it will happen. Charting only really works if you do it over a longer period so you can see patterns. By that point, we will be undergoing treatments.
I love my smartphone app.
