My LMP was March 5th, I have a normal 28-29 day cycle. DH bday was March 19th, around my o day. I'm sure we bd'd a couple times that week. We're not avoiding pregnancy but not trying to prevent it either, so we only use the pull out method of BC. On April 2nd I started bleeding, assumed it was AF but really light, almost no pink blood, just brown. That lasted three days. It was so light, a panty liner would have worked for those three days... This has never happened to me before. But since then I haven't seen the real AF. I took a HPT, EPT digital on Saturday night, it came back negative and I haven't taken one since. I've had only a few pregnancy symptoms off and on... Advice please?
