Ovulation help!

Hi!

I’m currently EBF my 10m old. My husband and I are TTC and I’ve been using the ovulation test strips. I get big fat negatives every time I take one. Not even a hint of another line 😩 I’m getting so discouraged.

I haven’t had a period since I found out I was pregnant with my son.

Any advice? Suggestions?

TIA ❤️
