How To Determine To Date Of Conception?
Question: I need to know which date I concieved. My LMP was on 1/30/15. I had sex on 1/28/15 and 2/21/15. On 3/3/15 I had bleeding for 1/2 day. Which date would be my conception date? Thanks!!
Brief Answer:
1/21/15 likely date causing pregnancy
Detailed Answer:
Hello ,
Thanks for the query to HCM,
It is definitely not 1/28/15 as you had menses after that which removed the endometrium completely decreasing any chances of pregnancy following intercourse on 1/28/15.
The most likely date which caused conception and fertilisation thereafter is 2/21/15 which is well within your fertile period when ovulation would have occurred. You had an implantation bleed on 3/3/15 if the urine pregnancy test is positive now.
The gestational age is usually calculated from the LMP but the ultrasonological age gives a fair idea of the date of conception. So an initial dating scan is imperative to zero over the actual date of conception if your previous periods have been regular and you had good cycles.

Thank you so much for your detailed answer! I really do appreciate it. Since there was the bleed on 3/3, I am guessing it also could have been due to having sex on 2/27 as well and becoming pregnant?
Brief Answer:
get serum beta hcg test to confirm pregnancy
Detailed Answer:
if you have not got the pregnancy confirmed yet then get a serum beta hcg test done now and if the test is positive then you are pregnant for sure.
if your assumptions are based on guess work then please get it confirmed first.
