I am late by 3 days so far. I have no PMS symptoms but I do have crazy amounts of mily/clear mucus discharge. The amount of discharge I'm having is getting scary, it soaks through my underwear. I woke up this morning with horrible back pain to the point where I couldn't breath, woke up extremely gassy and I had to crawl around the house looking for meds. I took a couple of midol thinking it was PMS symptoms and it worked. The pain stopped but I have have this crazy amount of discharge coming out. I have to wear a liner. And I'm not pregnant! That would be physically impossible . I'm full time college student and a little stressed so I haven't had sex in a while. Any ideas what it could be?
