HELP - New to tracking ovulation

First time tracking ovulation with clear blue testing

CD 22 - Peak fertility on digital test

CD 28,29 & 30 - didn’t test, but spotted for 3 days only. (Thought maybe implantation or start of period but was very close after peak ovulation test???)

CD 30 - TODAY / still no period - negative test.

I’ve struggled with the regularity of my period, i usually spot for a few days then nothing before it comes back again lightly.

I’m starting to feel worried that conceiving may be a problem for me, does anyone spot before their period and stop for a days before getting it again? Now I’m concerned that maybe my luteal phase is very short.

Thank you!
