No period in 30 days!

Vandielou
That's right I haven't had a period in 30 days. I stopped taking BC at the end of September because it was giving me high BP. So I just decided to discontinue it. Since then my husband and I have not been using any kind of protection. I've taken 3 pregnancy tests. All negative. But lately I have been feeling just a little bit of nausea, mild cramping. Nothing that hurts but I can feel it. Some acid reflux and slight constipation. And today I noticed some white discharge. My husband insists I go to the doctor but I don't think I need to just yet. Has anyone else experienced anything like this?
