Pregnancy Conception Date: Calculating Due Date with Irregular Cycles

Question
Hello, my name is Karyn. Im 24 years old. I recently learned I am pregnant. I was unsure of my LMP because i have an irregular cycle and I last started spotting on July 20, 2009. I thought it was a normal period since I was on the Depo shot as a form a birth control but the spotting only lasted about 2 days, which my norm is 6 to 7days menstruating.I had sex starting July 10th. B efore that I havent had sex since mid May. I guess my question is did I become pregnant on July 10? Or was is the 20th? I cant figure out if I am really 9 weeks or 10 weeks pregnant? When was my actual date of conception and what is the actual pregnancy date? I am so confused about this!!! Can someone PLEASE help me? And is my due date?? I don't have my first doctor appointment until a week and a half from now and I am very anxious! Can someone please help me?!?!?!?!!?!?!

Answer
Hi Karyn,

Thanks for your question. It's really hard for me to tell you a conception date or due date over the internet. I would recommend that you go to a pregnancy resource center and get a free pregnancy test there. Go to http://www.optionline.org or call 1-800-395-HELP to find a location near you. If you email me at CHERYL51@aol.com we can talk more. I will also look on the internet and see if I can find any information on the conception date calendar. So email me and I'll write back. Let me know when your doctor appt is as well.

Sincerely,
Diane Cheryl
