Had a scan on my ovaries about 16 days ago was getting alot of pain.everything was fine the nurse said she could see folicals on my ovaries and that the lining of my womb was thick.i was due to have a period.i did a pregnancy test 3 days ago but was neg. the next day had some weird bleeding thought it was my period but it is hardly anything and is a brown colour only a tiny bit when i wipe after going to the loo. could i have done the pg test to early and maybe i am pg.
