So after bleeding for 23 days and being on CD 20 I took a PG test & got a Negative. Not what I hoped it would be but it just means we need to try harder.. I have been having bad pressure and pain in my lower abdomen,left side and in my vagina. Idk what it is but it hurts so bad I cant move.. :( I wish I knew what was going on.. I want a baby so bad.. 😢💔 Im so scared!
