forgive me for being slightly obsessive, but a little confused. first month ttc - did the deed once at OV time (and pretty sure i ov'd). last week or so masses of pg symptoms (boobs, feeling sick etc etc). these still haven't gone - tested at 10dpo and got a bfn.
then on sunday (12dpo) i thought af had arrived but it does seem extremely light - just a small amount of blood over past few days, nothing at all like normal. (though this is first 'normal after pill, so i guess it could be that). COULD this be an implantation bleed and should i test again, or am i just being crazy - surely it's too late? if i didn't have this constant nauseous/swollen tummy feeling i wouldn't be so preoccupied, but it's like i've never felt this before - help!
