Im so confused

Hello everyone,

Please no horrible comments!

Sorry if some people find little bits to much information.

So yesterday I had a 4d scan which was absolutely amazing having a little glimpse of my bubba! I’m just shy of 7months now

But I’m having 2nd thoughts about the father.

So before any horrible comments yes I was in contraception religiously but still fell pregnant so was a massive shock when I did find out

So I slept with my ex and the other potential father just a few days apart from each other my ex didn’t cum ( yes I’m aware Pre cum can still get you pregnant but I never fell pregnant in the 4 years of us being together so didn’t think any thing of it)

other potential father who is aware I’m pregnant but hasn’t been massively support I’ve had a lot of trouble up until recently from him and has only jist decided he wants to be involved I was very certain that my little boy was his!

BUT after having my 4d scan yesterday I don’t feel like he looks like him in anyway and has more features looking like my ex for example his mouth/lips & nose so now I’m doubting my self ALOT what do I do?

I know paternity test is my best option but I’m scared and super worried now!
