I stopped taking the pill two months ago. My cycle has always been 28 days long, however last month it was only 26 days. We had sex the day my cervical fluid changed. About a week later I started getting nauseated every day. I haven't been feeling tired, nor are my breasts sore. Is it possible that I am pregnant? How soon can I take a home pregnancy test?
Hmmm, interesting! As you know, cycles on the Pill are pretty much always 28 days, so you can't know what to expect when the Pill is discontinued. Noting cervical mucus change can be helpful in figuring out when you might release the egg, since ovulation can be a little unpredictable. The first few ovulations after coming off the Pill may be earlier or (more commonly) later than day 14.
For many moms-to-be, breast soreness is the earliest sign of pregnancy, since it may start before the missed period. Nausea typically doesn't begin until week five or six from the last period (three to four weeks after conception). Fatigue starts around that time as well. One general rule is that most pregnancy symptoms don't begin until after the pregnancy test would turn positive, since pregnancy hormones detected by the pregnancy test are the cause. On the other hand, I have certainly talked to moms who "knew" the moment they conceived, or who had pregnancy symptoms starting earlier than average.
So, yes it is possible you are pregnant. As to when to test: some cycles where there isn't really going to be a pregnancy have a brief rise in hCG than reverts quickly to normal. If you do the test too early you can get a false positive, and then get your hopes up only to have them dashed. Also the pregnancy test may not be positive until the period is missed, and if you run it too early you may get a false negative, and be disappointed when actually you are pregnant. I usually recommend waiting to run a pregnancy test until your period is due or you are having clear-cut pregnancy symptoms. Good luck to you!
