Trying for baby #2 our daughter wants a sibling

Me and my husband have been Trying for baby #2 for about the last 6 months. Ever since i got off birth control 2 years ago after having our first child we have not used condoms or any kind of protection. Just recently in the last 6 months ive been tracking my period and taking prenatal pills. I just bought some ovulation prediction test that im going to start as soon as im done with my period. Im willing to take any advice. Our daughter is asking to have a sibling and we really want to expand our family. I just remember how hard it was to get pregnant with our daughter it took nearly a year and a half and also a miss carriage before i was strong enough-to carry our daughter with the help of a steroid. I just hate seeing AF each month.

Please Help A Mommy Out lol .
