Feeling pregnant

Hey I found out I am pregnant 3 days ago I didnt test because of symptoms or missed period I took a test because I just had a "feeling" that i was and they all came back very positive. I've woke up this morning and the feeling has gone I dont know why but I just dont feel it anymore, I've had a lot of losses so i dont know if it's just my mind playing tricks but i wondered if anyone else has had this and everything has been ok?
