Technically the soonest you can have symptoms is after implantation...they say anything you feel before then is just the hormone change and has nothing to do with pregnancy. I think implantation happens somewhere between 7-10 days after O. But I have read some women say it has happened earlier. There is this thing called an implantation dip, where for one day your temp dips on the day of implantation and then goes back up. But then there ARE ladies who say they just KNEW they were pregnant after conception...I can't imagine!!
I check my cervix, but don't really take it too seriously. I always say I'm not going to then I do. They say it's not a reliable way to predict pregnancy since every women is different. I think where it can most help you in this process is predicting O.
My temp did go back up today, not back up to the temp that it has been..but a very obvious spike up even with temping an hour earlier than normal. Hoping that I did have implantation dip and this crazy TWW will end with my first BFP! Trying to think positive
I know you can have an implantation dip and end up with AF, but I've never had it before.
Here is what FF says about the chart settings Advanced and FAM:
The
Advanced Detector is our recommended detector and the default for all charts. We recommend that you keep your chart on this setting. This detector takes all your fertility signs into account. It uses the computing power of our servers to actually scan for patterns of ovulation on your charts based on the many patterns that we have encountered through our years of experience. Once it has determined your most likely ovulation day based on all your fertility signs, it then determines a coverline (the horizontal line across your chart) with a reasonable value to show you your biphasic (ovulation) pattern. Our advanced detector simultaneously takes into account all signs and data you enter to determine the best interpretation.
The
Fertility Awareness Detector is based on the Fertility Awareness Method (FAM) as it is widely published (ovulation is detected after 3 temperatures above the previous 6) with some enhancements. This detector is best suited to those with regular chart patterns who are already familiar with this method.
So it seems like FAM changed my O date to CD15 because of the dip. But the Advanced method noticed the dip but also took into account everything else and assumed it was a fallback rise.
I'm feeling CRAPPY this morning. Have had a sore through since O, not bad, but it's just irritating. Had a stuffy nose this morning. And just have been sore and tired. Tossed and turned last night night and my lower back hurt SO BAD (although it feels fine now) and I slept wrong on my neck the other night and it still hurts
I'm just, in general...TIRED. Oh and to top it all off, at work this morning at 630am all by my lonesome and we had an earthquake!!!! Haha...I grew up in CA so I've been through some big ones, but it was centered near my office so it was just tons of shaking, when we normally sway. I was pretty scared...ran out of here so fast!!!
What a way to start a Monday :/
. I was using my temp from first wake up after 3 hrs sleep even if it was in the middle of the night, versus using the one around the same time each day. So I changed my temps to the same time ones and my chart seems to make more sense. Its tentatively saying I o'd on CD13. But temp went up again today to 37.00. I attached my chart for you to have a look at. As I've said I am not really convinced of o on CD13 as I only started getting fertile signs most recently.
