Haven't had a period all month of June.

I'm pretty sure all the pregnancy tests Ive taken are negative. I had one faint line that got darker out of the time frame so I'm assuming that's negative. Anyways. No period all June. My lmp I believe was may 19-24 I'm not exactly sure. I haven't been tracking anything. We're trying but not trying due to we have a two year old and an eight month old right now but the reason I'd like to go ahead and try now is because I have pcos I developed it after having my daughter and I was told theres a big chance I won't be able to have anymore.
