I think dd may have reflux and I am so over only getting 2 hrs sleep a night

We have her bassinet inclined a bit but its not helping but she seems better in her rocker

She screams as soon as I put her down mostly at night and I can tell she is in pain

She wants to be fed and cuddled all the time

She spits up before, during and after feeds but not excessively

And I can hear her choking and refluxing when she is lying down

Should I try baby gaviscon or thickener first to see if it helps or Just go straight to the dr and get something else?

Dd is 2.5 weeks old
