After 4 months and 13 days after having my little man I came on my period ,not long after I had sex and after couple of weeks after my period was expected and I didn't come on , so I waited two weeks after and took a test and one came back a faulty pregnant apparently , so went to take two more and came back not pregnant ( clear blue digital) , I wasn't show about this so went to doctors for a pee test to be sent out , that also came back negative so I have waited to see if I come on this month and I still haven't so far , my little man is 6 months now// Any ideas on what I should do ?? Or any suggestions on what it could be please .
