Need some advice.

Vanessa
Alright I feel like i'm going crazy...so I took a test this past Sunday I got a faint line but you can definitely see it. I took another one same thing faint but noticeable line. My Af was supposed to arrive Sunday. ...I'm regular and never late...it's now Tuesday and sill nothing. I also went to the doctors yesterday got a test done negative. ..did ANOTHER at home test this morning and guess what...nothing. So needless to say I'm confused haha. I thought our hcg levels were supposed to increase everyday. HELP! Any thoughts??
