Yanisha

Af was due Aug. 20 it did not show up, I spotted on the 22nd & then a light to medium flow on the 23rd. Okay cool. I O'd Aug. 5. BD of course. Aug. 18 got a vfl, Aug 20 vfl and I took another today & got another faint line! My sister told me she had three full periods when she was preg. with her 1st son (he is one and healthy). So hopefully others have had this problem and I'm not the only one kind of freaking out. Calling Doc tmr morning.
