What does this mean as far as due dates go?

My last period ended on the 7th January. We have been trying for baby no. 2 for a while but as I was still breastfeeding the one night time feed, we think I may not have been able to conceive. I dropped the night feed on the 1st of Feb. My period should have been due on the 4th Feb but never came. I tested negative to a home pregnancy test on the 5th. We have had sex numerous times, known dates; 3rd, 10th, 14th Feb. Home test on the 15th Feb turned out positive.
What does this mean as far as due dates go? Seeing as though my first day of last period was at the beginning of January!

an ultrasound will date it best, but I would guess the 15th of October, congrats

I've heard this site has an EDD calculator. You calculate based on the BEGINNING of your last period.

Yeah, there is a due date calcutor on the main (non-forum) website for APA. It goes from the first day of your last period. I'd guess you'd probably be due sometime mid-Octoberish. Congrats!

You must have ovulated later than normal (were you having regular periods before this?). Your doctor will probably want to do an early u/s to date the pregnancy since your BFP came so long after your last period.

Yes I had had 2 regular periods 28 days between end-start cycle. I guess the only thing to do is see our dr and have the ultra sound! Then I can get excited. Thanks for your posts ;)
