GROUP B STREP TEST

Okay. I’m 36 & 4 days. Yesterday I had my group b strep test and I swear the ob went up so high while swabbing. It felt like I was being scratched from the inside. She was going in circular motions and I was screaming internally. Anyways. I had a strong urge to use the bathroom after so I went to the bathroom and literally had the worst burning sensation while peeing along with spotting. Today after going pee like 4 times throughout the night the burning sensation is going away but I’m having a lot of cramping/lower back pain. Have any of you experienced this? I recently lost a little bit of my mucus plug a few days ago. 😭😣🤭 HELLLPPPPP.
