Hi Dr.,
  My husband and I had unprotected sex on april 8th and he ejaculated inside of me. Now my menstral cycle was supposed to begin april 9th but has not happened. It started on march10th last month and i am usually consistant. But every february my cycle ends up changing. I got it Feb. 3rd and in march it moved over a few days. Is there a possiblity of pregnany for us since my  cycle changes?

Anything is possible, but it's not really likely that you would ovulate that close to your period. Generally, you need about ten days between ovulation and menstruation for the egg to implant (it's called the luteal phase). Less time than that, and the chances of implantation decrease dramatically. Given your irregular cycle there is certainly a chance you could have gotten pregnant...but if you had periods on 02/03 and 03/10, you'd have a 35-day cycle...meaning that in April you wouldn't get a period until 04/14. So, when you wrote this post, you weren't due for your period yet. Anyway...all you can do is wait and see what happens. But I wouldn't worry about it for a couple of weeks! Stress can delay your period, also!

Thanks for that cuz honestly  my cycle is always changing. I used to be on Depovara and I didnt get a period for 6 whole years. Now that I have been off of that shot my periods are constantly changing. I ended up menstrating Late saturday/sunday morning. But by monday I bleed thru a super absorbent tampon in less than an hour. Now during my first pregnancy I had my period for 3 months and bleed regulary. and I took 3 home EPT test and each read negative. I took a First response test which read negative always. But I am scheduled for a GYN appt May 1st. I also have been experiencing severe sleep deprivation and nasuea, mild headaches and back pains. So opefully I can get some answers during my appt.

Thanks

Well, in an ideal world you are supposed to ovulate 14 days after the first day of your period. However, if your period is early then you will ovulate early. And if it's late, you will ovulate late. Since your periods have been a bit irregular lately, tracking ovulation (which is the point where fertilization can take place) can be a bit more tricky. You might have very well ovulated just before you were about to start. Also, every time you have sex you have a 25% chance of getting pregnant, especially during ovulation. Just keep an eye on it for a few days. If your period is pretty much normal, you may not have anything to worry about until next month since it was literally the day before you were supposed to start. If your period happens to be very LIGHT and is shorter than normal your body might be making the changes into pregnancy. Just remember that sometimes women will bleed very lightly throughout the first few months of pregnancy as their body changes. It can happen. Good luck and keep us updated.

we are not doctors. there is a 25% chance of conceiving in any given cycle when you have had unprotected sex.
