I'm on CD22 out of a 28 day cycle. I've been having cramps that feel like menstrual cramps, back pain, migraine, urinating more than usual and have been getting a bubbly feeling down there, almost like she's blowing bubbles out. I used an opk this cycle and should have ovulated on CD14? Has anyone else experienced that bubble sensation long before their period was due? Did anyone experience these symptoms before they got their BFP?
