Give me Peace of Mind

Question

My period comes every 24 days for the last 14 years of my life. I got a period 10/21, 11/17 then had sex on 11/27, 11/28, 12/2, 12/3, 12/7 and 12/8...I took a Next Day pill on 11/30 and I had a 4 day period on 12/11. Negative pregnancy tests on 12/2 (First Response EPT), 12/7 (Dollar Store Brand---with the pee dropper), 12/10 (Dollar Store Brand with the pee dropper), and 12/27 (Target Brand)
On 12/21-12/26 I had sex. Got a positive pregnancy test on 12/31 (First Response EPT).

I went for an ultrasound on 1/13 they only saw the fetal pole and sac
I went for another one on 1/30 they detected a heartbeat said I was about 7 weeks.
I went for one on 2/10 they said I was 9 weeks...gave me a due date on 9/13/14.
So far I've been measuring up according to my ultrasounds... I just want to know when did I get pregnant? I'm nervous because I'm hoping its 12/20 or later, but I JUST found out that the Next Day pill doesn't stop ovulation but just delays it...You can judge me but please give a helpful answer with the judgement...

This discussion is related to (help) when did i concieve!!.

so since i started my period at 14 years of age it has always been irregular. i am now 20 and it's still the same. my cycle is usually around 39-45 days, which to me is normal. anyway my last period was on december 3 until december 7 (which is roughly five days each time i get my period. the bleeding in between those days are on and off and on the first day i get cramping but goes the next day). i had sex on the 16 and 17 december 2014 and was fine. but until yesterday (6 january 2015) i had very light bleeding and later had very bad stomach cramps i had to lay down and even that didn't help. (bare in mind my cycle is 39-45 days. so its atleast nearly two weeks early for me to have my period. or is it?) which prevented me from sleeping well at all last night. woke up very tired and dizzy. today the bleeding is bright red and was moderate in flow. had a bit of clear discharge too. i also felt like i was going to vomit but i didn't, had healthy food today, and drank alot of water. i also am a bit warmer then everyone else and when i lay down i seem to always have gas. i've never gotten this between periods ever! went to doctors and did a urine test and it said i wasn't pregnant. he said it could be that i have an STD, i'm getting into a regular monthly period or that i'm having implatantion bleeding. (i find implantation bleeding impossible since i had sex nearly three weeks ago.) i'm praying it isn't an STD i recently changed sexsual parners. ended a cascual thing with this guy in august 2014 (thats the last month i had sex with him). and sleept with someone else on the 16 and 17 of december 2014. but before i sleept with this recent companion my periods always came on time (even tho they are irregualr, i have a chart to record my period cycles.) i have to wait five days for the results and i just cant wait that long. does anyone know what this is??????????? :/ :( still have the cramps in my stomach its bareably at the moment but wasn't earlier on today!!!

Sorry you're worried. So easiest way to think of it is you made an egg after 12/11, assuming your last day was 12/14. Very unlikely you were pregnant before that, because you had a normal (assuming?) period. It makes sense to me that you conceived after 12/20, if the last time you had sex was 12/8. Your period, if normal, sheds the old egg and creates a new one. So conception of an old egg, after a period shouldn't happen. Anyone correct me if I'm wrong, but that's how I look at it from the dates.
