Ok so I'm on cd 47 & 17 days late... all tests I've taken are negative. I've been havon cramps all over my stomach since yesterday (not like my af cramps) ... I just used the bathroom (sorry if tmi) I found a dot of blood... I haven't had any signs of af... I just don't know what to think... my af wasn't suppose to start again until the 13th of June.
