im on the pill an iv messed it up alot lately but my periods started gettin regular before i went on holiday. since ive been home my breasts hav been really sore, my skins gone really bad an i keep gettin cramps as if my period is due an then nothing happens. ive done a pregnancy test a while ago but im worried incase im too far into the pregnancy for the test to pick up the hormones, do they still pick it up throughout pregnancy? any answers would be great.
