Have any of you ever gotten sick and been put on steroids and antibiotics and these made you miss your period? I was supposed to start on 1/16 according to glow and I'm rarely ever off by much. Maybe a day or two. But never like this. I've taken so many tests and they're all still negative. I've been cramping a tiny bit here and there, my boobs are just a little bit sore but nothing out of ordinary for period time. I did have back aches a couple days ago. So I'm having symptoms saying my period is coming soon I hope. Hubby and I decided to wait it out a few more days and then we'll go get blood done. I was curious if this type of thing has ever happened to anyone else? Is this common?
