we were ttc no.4 last month but towards end of month decided not to due to various factors. Anyways Af hadnt turned up couple days past time so I did a test which came up negative. 3 days after that what I thought was Af turned up, bleed as if about to start but after about 3hrs it stopped. Since then nothing and its now 5 days after..so do I need to test again or have I just been lucky and had a very rare light af??
