BFP on my "off" month after Femara/Letrozole

Ashley • Pregnant with child #4 after 16 months of unexplained infertility. Just trying to look towards the future. 💋💍🥀🌮🍕🍻🍾 I love my 3 children, MTV's The Challenge & Greys Anatomy!s
I got my BFP this past weekend. 1 year of unexplained infertility & 3 rounds of Femara/Letrozole.
I did Letrozole in March, April, & May. With no luck.
I am curious if in June (when I conceived) if the Letrozole would have effected my ovulation? I did NOT take it in the month of June.
My biggest thought is TWINS because I popped positive on a DIGITAL on day like 26. I'm a 30-32 cd girl....
So super early!!
