Am I even pregnant anymore?

So I am 23 weeks & 4 days pregnant.

& paranoia of what ifs keep surrounding me.

I thought that after I had my anatomy scan At 18 weeks that all my fears would be put to rest but no!

I’m already a big girl so I’ve had a tummy before pregnancy but I take weekly bump pictures & I don’t see any difference.

I have no pregnancy symptoms anymore except being tired and sometimes nauseous

I don’t feel anything. Any time I think I feel baby moving I’m never too sure.

I’m a FTM so I don’t know what exactly I should feel.

I went to my doctor December 10th & he searched for her heartbeat after a few minutes he found it and told me that it sounds faint but it’s because the Doppler isn’t very good at picking it up on bigger people but it’s okay

I didn’t worry because at least he found it.

My MIL gave me a home Doppler & told me that after 22 weeks I should be able to find her heartbeat on my own. So last night I tried for a good 20 minutes & found nothing

To be honest i was probably doing it wrong but it freaked me out.

I woke up today and my stomach doesn’t feel as big & hard as the past few days.

I don’t have any cramping or bleeding but I’m freaking out ...

What do I do?
