Undefined's Trying To Conceive Wish

20 y/o wishing she can get pregnant b4 she turns 21 next year. Lord plz let her miss her period so that she can get a pos result on a hpt or blood test. It's hard to know when you ovulated or not. And praying she doesn't have infertility issues due to her stop taking the pill in April of this year, and having her cycles irregular for the third time. Not having health insurance to track her bbt or opk.
