Wasn't sure how to title this!!
I have a 4 year old DC with exP. We split amicably shortly after DC was born. Both single for a couple of years, then both met new partners. Me and exP get on incredibly well. Very good and equal co-parenting relationship. We are happy for each other having met our respective new partners, always have a cuppa together at DC drop offs and a quick 10 mins chat. We work far better as co-parents than we ever did in a relationship.
Present day. Me and current DP moved pretty fast and moved in together when the pandemic hit. We've only been together a year, however it has been a very intense year. I actually posted a thread on here gushing about how I'd found the one after 2 weeks 
I found out today I am pregnant, around 4 weeks. Haven't even told DP yet as he's away with work til Wednesday, but now my 4yo DC is in bed I'm overthinking every aspect of this!
DP will be absolutely thrilled. He's older than me and nearing 40, doesn't have any children and is absolutely desperate for a baby.
However.
I'm worried about telling exP about the pregnancy, whether it will change our co-parenting relationship.
And I'm worried about what my family/friends will think having 2 kids by 2 dads within 4.5 years 
I guess I'm a bit scared of being judged.
I'm also a bit worried as DP and I planned to get married this autumn, just us, our mums and my DC. We haven't booked anything yet. However now I'll be 8 months pregnant(!) and I don't want people to assume we'd be marrying just because of the baby.
Thoughts? Experiences? Anything welcome really. I'm just brain-dumping all my worries here!
