Could the use of probiotic drops (like Bio gaia) be beneficial for my daughter in this kind of situation?

My baby is one month old today. I suspect she is having a little reflux. She "chews gum", sometimes seems uncomfortable after limp. At night it's hard ++ to put her down after a feed, even if I keep her upright for at least 15 min. She raps ++, the milk goes up in her throat, and if I let her she ends up crying. She sometimes regurgitates (day or night) but small quantities, and often curdled milk. I don't see her doctor until she is 2 months old and I would like to relieve her before that. I don't think she is colicky (no intense crying episodes every night at the same time) but she seems to have stomach pain sometimes (has gas, forced but no stool, squirms), occasionally during the day. She's exclusively breastfed and I'm already doing the other stuff (elevating the bed, daytime carry to sleep upright, burping regularly-she has trouble with it sometimes, etc.). Thanks!
