I hope someone here can help me out.....
I am 23, my husband and I have been trying to get pregnant for 6mnths now. Before trying I was on and off birth control for about 2 years...
I have been taking folic acid and prenatal vitamins for almost 3 months. Last month I started my period on the 26th which came with really bad cramping and headaches, not to mention heavy bleeding. However, I started my period on the 20th(almost a week early). I had no warning symptoms...On 20th I noticed light pink bleeding. On the 21st I was alittle heavy not to much but it wasn't red it was more a brown...For the last two days only light pink when I wipe.....As if it stopped which for me is comepletly weird...I had breast soreness up untill 21st now barely any soreness....My stomach has been cramping alittle bit...However I have almost lost my belly button completly and in the last month and a half my stomach has changed I haven't really gained anyweight(except int the very front of my stomach)...The earliest appointment I could get was September 5th so I am really worried....I DON'T KNOW WHAT IS GOING ON.... I would really love some advise...

Thanks for reading...ANT
