Hi I'm spotting since 3 days. It's very liquid with brown colour. It's happening from day 19.. It's very unusual , it once happened in Feb this year and period was missed that month with neg upt, To induce period had to use tablets.. Trying to conceive since 5 years.. I have history of irregular periods because of high postprandial insulin.. But are regular since a year now.. So what does that spotting mean..? And also I'm having cramps like period and back pain.. Thank u
