Woke up to insane nausea

3dpo and woke up to incredible nausea and ALMOST threw up. I literally have a condition where im so scared of throwing up I can force myself not to more than others can. If it wasnt for that, I def would of thrown up. I sat in the bathroom for 30 minutes forcing myself not to puke. An hour and a half later in perfectly fine and currently am. And yesterday I was super crampy. I have it today too. And I've had the WORST time falling asleep the past couple days which is never a problem for me. I even tried tylenol pm which always knocks me out but didn't work at all last night and night before. Also in these two days I've had bad hot flashes, and constant feeling like I have to pee and I've felt like im getting the start of a cold..... I know its WAYYYY to early for any pg symptoms. But could it be possible????? I've already pretty much counted myself out for this month cuz I don't want to be so let down once again. But idk what all this could be????? Could it honestly be possible that im having symptoms so early if we conceived????? Plzzzzz no mean or rude comments. Im not stupid or uneducated on all of this. Just confused and want everyone else's opinion 😛 thank you in advance!!!!!❤💚💜💙💛
