***tmi* slowly leaking fluid? *pictures warning ⚠️ ***

Slow leaking fluid? I’m 35 weeks and 2 days but I lost a big chunk of my mucus plug today it was Atleast 2 inches and thick . Ive been 1 cm since I was 29 weeks this is my second baby but 3rd pregnancy. Been contracting since around 3-4 I know of on and off not consistent but have been and then I go walk around a shoe store looking for some stuff and I felt like what seemed like water come out but I know it came out of my vagina because I felt it and it was enough for me to feel it come out and wet my panties and then happened again when I went into a different store for panty liners to go home to see if that’s what it is.. idk but I’m still having contractions/maybe Braxton Hicks? Idk but been having them since 3-4 some I can feel very lightly and some are a little stronger . I know I’ve lost like my mucus plug over the last 4 weeks since 31 weeks but not in a big chunk like I did today just like enough to see but it was always smeared like texture not a big piece ? Any advice
