Cramping and Spotting

Mandy • 29 years old - Married October 2013 - Mom of Baby Girl Dec 2015 😊 Expecting Baby Boy April 2018 ☺️
Started spotting this morning and it it feels like I'm having period cramps. The spotting is light and brownish in color. Im also taking progesterone suppositories. My boobs stopped hurting and don't feel as firm and I've had little to no morning sickness.The nurse was very dismissive but I'm panicking.
 I've had two chemical miscarriages in the past year (oct 2014 and jan 2015). I'm five weeks 2 days pregnant. Please help.
