18 and pregnant

i am 18 and pregnant with my first baby! i am currently 23 weeks today. the last week ish i have been having a lot of pain on the bottom left side of my stomach right above my underwear line. it is very painful to where i can’t move until the pain stops. it last 30 seconds - 1 minute but happens consistently for about 10-30 min when it does happen. are these braxton hicks?

i tested positive weeks ago for staph b and was treated with antibiotics for it already, but my doctor said it can cause preterm labor so it worries me!

• it started last weekend on sunday night randomly when i was driving on a long trip home and woke me up from my sleep early this morning.
