Pregant?! Anyone relate?!

So during my 2 week wait i was feeling off, and i knew something was up with my body. Peeing extra and eating extra. So the day AF was to come i had severe headache and nausea and vomiting. 3rd day late i started bleeding. Lightly but a few clots(not huge). And uts not mt normal bleeding either! I talk to my sister and she said she had same thing happen and after she stopped bleeding, a week after she got a positive pregancy test. Her baby is now a year old. Just wanted to know if anyone has had this happen to them?! Would love stories or opinions!
