5 days late, BFN, No show from AF 😭

Lauren • I`m 25, been with my hubby 8 years, married just over 1 years, ttc 1#. Sending baby dust xx
Feeling so deflated today! I want to actually cry and just give up from ttc! Now heading in to my 10month. My cycles have been so long CD37-CD48! Last 3 days, BFN everyday, no even a faint line, so why won't AF just come 😭. I got the biggest positive OPK on the 8th Jan, so ovulated later.  I feel there is something wrong with me, but doctors won't investigate until April. Any advice ladies to keep me going? Any suggestion on regulating my AF and around fertile window. I can't BD every other day as I work nights and it just gets exhausting by the time my fertile window arrives around CD20-CD25. Love to here some successful stories 😘💞🙏🏻 xx
