"Ongesteld" means pregnant?

Hi lovely members,

This will probably be yet another topic about this subject, but I'd still like some clarity and maybe to hear your experiences.

I had my period last week... but it wasn't as long as usual. I was done after 2 days, normally it lasts 5 days. I had incredibly weird and painful cramps. I always have painful cramps during my period, but I've never had it this bad before. Now, after my period, I still have those cramps, I'm dizzy, nauseous, and have no appetite. So I wanted to ask if it's possible to be pregnant and still have 'period' bleeding?

By the way, I'm on the pill, so it's not like we're trying for a baby.

If I still feel like this in a week, I'll take a test, but I wanted to hear your experiences first. Maybe it's all in my head and I'm just overreacting...
