TTC HELP

Trista
Okay ladies, I have a question or two. My boyfriend and I recently started TTC. We've only been trying for about a month. I haven't got my period this month which was supposed to start on Jan. 15th. I've take ovulation tests and the reference line shows up indicating I've done the test right, but I had no LH surge meaning I'm not ovulating right now. I've taken two pregnancy tests, and they've both said not pregnant. I've never really had an irregular period, at least not since I was young and I'm 22. Any suggestions as to what is going on? I'm not really sure how to track my cycle if it's all of sudden off track now. Thank you so much everyone! 😊
Update: I've never been on birth control.
