My period was due Tuesday but I have zero sign of it. I took a test yesterday morning but it came back negative. I’m normally always on time with my period and can tell when it’s coming usually a few days before. I had crazy pms the days leading up to my predicted period but still have no sign of it. I’ve been feeling a little dizzy and gassy. I honestly don’t know what to do. Has anyone else had this happen and still ended up pregnant? Also my 21st birthday is Thursday and I want to know before hand so I don’t drink which is why I’m freaking out a little.
