I am the same, no period since the 17/01/2015, and shattered all the time. the first 2 times of pregnancy, i knew i was pregnant due to implantation bleeding (which i lost both of them), but this time there has been nothing. Some pains and feeling sick and sore boobs and very tired all the time. :-( I am gonna go to the doctors this week.
But good luck x
Sorry i forgot to add my SIL also had low hgc so after they saw baby she had to take a tablet everyday to help her hormones.
My sister in law never showed a positive pregnancy test the first 3 months of pregnancy i went with her to the doctors so many times.... they ended up giving her an ultrasound and saw a baby.
I also got negative for 3 weeks after my missed period i get a positive at around 6-7 weeks pregnant.
An ultrasound would be a more than effective way to prove if you are. Good luck and God bless :)
Have them do an ultrasound
