SO IM WORRIED. I have a period tracker. According to it I was suppose to get my period on the 5th of this month. On the week of the 5th I had lots of cramps but I was days late and didn't get it till the 10th.. I'm usually always on time so the lateness scared me. Well the first 2 days were really heavy and then it got super light and lasted maybe 2 more days after that. My periods last 5 to 6 days usually and I'm heavy til the 4th day. Now since Sunday Ive been so nauseous. Like ridiculously nauseous. From the moment I wake up till I go to sleep. I ate soup yesterday thinking maybe it would make me feel better and nothing. I've never been like this... Do you think I could be pregnant 😰 My first pregnancy I felt all the common symptoms and missed my period completely so that's why I didn't think about that this month but now with this nausea I Dont know 😕 I'm not doing anything different or drinking any medication that could be causing it..
