Hi,

A couple weeks ago I did a home pregnancy test and it came out positive but when I went for a blood test it was negative the following week, now it's the middle of February and still no period since December I do have an undeactive thyroid but am on medication and was getting my periods up till December, should I try and take another home test or am I definatly not pregnant? And with not getting my period am I fertile enough, how can I tell when my fertile time is? Thanks! Any advice is appreciated.
