7 weeks today since my last period....

[MissyP]

I havent had a period since jan 21st. It lasted 3 days very light. I thought i had O'd around feb 4th-6th as i was having very stretchy egg white CM. I dont chart though since im not really trying to conceive (not preventing either) so im not absolutely possitive i did O. Either way i was expecting my period to show on feb 18th which puts me at 3 weeks late. I took a test at 1 week late but it was neg. I havnt gotten myself to take another one.. i dont have any symptoms except for some bloating and heavyness in the pubic area. I guess my question is, has anyone completely missed a period and not been pregnant? Or were you pregnant and it didnt show up on test til later? Thanks in advance♡
