Help me figure out my due date please!

[Rosie0812]

Hi everyone,
I have very irregular periods there are roughly about 55 days in a cycle. I think me and my partner conceived on the 19th September 2020, I then saw "pregnant" on a clear blue digital on the 30th September (first test I took) over the moon I couldn't even believe it. I am struggling to work out my due date as most of the calculators online are based on regular cycles so I get inaccurate results.
Please can someone give me an idea.
I have an early scan booked for next Friday the 16th to see if everything is okay so I'm hoping they can also help work it out too.
Thank you everyone I really appreciate any help! ❤️

Hi @Rosie0812, were you tracking ovulation this month? When you say you think you conceived on the 19th, is that because its when you DTD or because its when you ovulated? If 19th was ovulation date, I think you'd be due 11th June.

Hi, i conceived 20-23rd September and my estimated due date is 18th June 2021 so yours is probably similar. Congratulations!

Getting a pregnant (assuming digital?) 11 days after sex would be unusual I don’t think. Digital tests aren’t particularly sensitive.

I think. Not I don’t think🙈

Agree with @Sexnotgender digitals don’t usually show that early so you’re more likely a bit further along.

When you have a scan they will be able to date it accurately

Get a clear blue test that tells you how many weeks? Think it only goes up to 4 but might give you an idea. Good luck!

Thank you everyone, you've persuaded me to get an early scan to check how far along I am, it is this Friday coming (16th) so I'll keep you all updated I'm so excited. Congratulations @babblebeee, is this your first pregnancy, it's my first I'm super nervous. ❤️

Thank you. It's my second. Very exciting indeed

@Sexnotgender I have recently got a 'pregnant' on 10DPO on a digital so it's not impossible. Can't see how it's wrong as I got +OPK on that day, and we only DTD then.

I had a similar experience OP - I think I'm 5+5 weeks at the moment, but if I go off my last period date I'd be considered to be almost 8 weeks because my cycles are irregular.
