Very late

Hello ladies, I am new to glow and looking for some advice. So I am over 2 months late, had a negative blood draw, and many negative pregnancy test. I have taken ovulation test and some said I had a surge and others said nothing. My husband and I recently decide to start trying. Since my 2 daughters r 7 and 8 and we want one of r own. I am very worried. Nothing has changed with me, haven't gained weight, been stressed or anything. Any help or advice would be great. Thank you kristina.
