Katie Woo hoo for the positive OPK!! Get busy mama 
I'm hoping we're cycle buddies again this month. I got my first positive OPK Tuesday night. I am 1-2 DPO today. Even with temping and the OPKs, I feel a little less certain this month and am still wondering if I O'd on Thursday or perhaps yesterday. Assuming I have a higher temp again tomorrow, FF will place O on Thursday. Either way, I feel confident that we're covered and timed things perfectly this month (we either got -3, -2 and -1 or -3, -2 and O). Interestingly, I used Wondfos and First Response OPKs this month (had a FRER coupon!) and got sort of contradictory results. I used both twice a day, morning and early evening. By the FR OPKs, I didn't get a positive until Thursday morning and it was positive again yesterday morning (Friday). With the Wondfos, I got a positive Tuesday night, both times Wednesday and Thursday morning it was negative. Basically, I am glad I had both and the temperatures to go off of. Officially in the TWW!! I am very excited and feeling great about our chances this cycle. My Ob/Gyn said things looked perfect. She said, "you just need to wait for that perfect egg!" Here's hoping that we both caught that perfect egg this month 
Fx Ladyelms!! I agree, I think CD 11 or 12 O can still result in a perfect, beautiful baby. PokeyAC said last month her current pregnancy is the result of O on CD 12.
A big 
to Publicnerdity, Writeonyogamama, Crunchynerd, Marie and Primaljoy (and any of the newcomers I may have missed)!!
Marie Timing in DPO when you can get a BFP vary from woman to woman, with each pregnancy, and by the sensitivity of the HPT (home pregnancy test) you're using. Here's a link I have shared many times to stats on sensitivity of HPTs by brand http://www.countdowntopregnancy.com/pregnancy-test/brands.php Within each brand's info, you can look at the sensitivity of that brand by DPO. Ultimately, it also comes down to when implantation occurs, as you need to be producing Hcg for the tests to detect it! Implantation varies from 6-12 DPO (days post ovulation), with most pregnancies implanting 8-10 DPO. But with that range in mind, and knowing you would be able to detect a pregnancy a few days after implantation, the very sensitive HPTs (like FRERs) would most likely give you a positive if you are indeed pregnant by 14-15 DPO even if implantation occurred on 11 or 12 DPO. I am a little confused by your post, you said you knew you were pregnant last month because you were 4 hours late? Did you mean 4 days? Most women, even the most regular, who can anticipate AF by hours (I know, I used to be that regular) , can vary cycle to cycle by hours or even a few days. Everyone has a wonky cycle every now and then. All that said, you could certainly be pregnant this cycle and a mc can throw timing off in the following few cycles. What brand of tests have you been using?
Sending out lots of 
and 
to all. I hope to see to a lot of BFPs this month!!
Fx for next month.
