I have posted in this forum recently about how I plan to start ttc in a year from now after I am married. My fiance and I have recently pushed our wedding back by an entire year. So we are now not getting married for two years (because we procrastinated too long and don't feel we have enough time or money to plan a wedding for next summer). I have not been trying to get pregnant and up until recently we have been using condoms. About 2.5 weeks ago we didn't have any condoms so we just used the pull out method and we have used it a few more times between now and then. I know that it is not considered a reliable form of birth control and I know that there is a decent chance of getting pregnant but I was wondering does anyone know how much of a chance? My period is pretty irregular every month and I can't tell if I am late or not but I feel like it has been quite a while since last time. We are not in the best place to be pregnant right now witch is why we are planning to wait. But we would be able to manage alright if we were. I am just wondering what my chances are and how am I to know how long to wait before taking a test if I can't tell weather I am late or not? Also I am a little worried if i am pregnant I don't have a doctor yet so I have no idea how long I would have to wait to see one!
