I've been ttc for 2.5 years now and always get my period right on time which lasts 4-5 days and the first 2 days are super heavy.. Fri night I barely spotted, yesterday got it on time but it wasn't as heavy... And now today its almost completely gone???  I had tested on Fri AM and got a negative test. Has anyone ever got their period (or bleeding) for one day when it was due but ended up with a bfp?? So confused!
