When did I conceive, my due date is either 29th June or 4th of July. My last period was 24th sept however was only 4 days.

CRL was 7 weeks on the 16nov via ultrasound,

HCG was 50 on October 19 via blood

Did I conceive at the start of September (& it have been a heavy implantation bleed for 4 days & not a period)?

Or the start of October??!!

We were actively trying in October, however my urine pregnancy test came back Positive at what would of been 9dpo for that month of oct

and I’m unsure if that’s too early??? It wasn’t on an early test.
