First things first, if you are ttc and you aren't sure when you will be ovulating. You should always have him ejaculate in you, because you never know
Soncondly, I understand your frustration. I've been there. When we first started ttc and I went off the pill, I was bleeding every 10-15 days. It was awful! And now I'm on day 90ish of no period...
Anyway, If you are having trouble knowing when you are ovulating (or not ovulating at all) I suggest you start tracking your bbt (basal body temperature) You take your temp first thing in the morning with a bbt thermometer and put it in a chart. You can tell when/if you are ovulatin by this. And it is pretty much the only way to know.
It is pretty easy to do. And the best part is it only costs about $7 for the thermometer and that is it! So, you don't need to worry about insurance.
Go to fertilityfriend.com. They offer free charting. When you sign up they give you a tutorial on how to do it, and what different things mean. A lot of us here chart so if you have any questions, we should be able to help!
I also suggest you start taking prenatal vitamins if you aren't doing so already
Good luck!
