I cant work this out!

[clomariejay]

So my last period started 3.10.2022, ended around 6.10.2022.
i have a 28 day cycle always done!
Which makes me due on 30.10.22 31st ish
i was expecting my period for a while as we only DTD on the 14.10.22 and that one time only all month!
iv just today took a clear blue weeks indicator and it says 2-3 weeks since conception, how does this work? 3 weeks ago would have been 5 days after DTD, and it cant possibly be 2 weeks ago?
so confused
help anyone x

If your lmp was 3rd October that puts you at about 5 weeks and 2 days which lines up. Clear blue isn’t that accurate to tell you the day because hcg increases at different rates for people. Sperm can stay around for up to 5 days afterwards. If you had a typical ovulation on day 14 that would be about 16th october which is only two days after you dtd. Even if the ovulation was later your dtd covered a window.

that makes sense, thankyou so 2-3 weeks would be correct for around this time then
