Ovulating... No BFPs... WHATS WRONG??

Samantha
Hi all! So I've been trying to conceive for 6 months. I was very naive at first thinking "hey I'm only 23 I will get pregnant easily!" Also my sisters both got pregnant on their first try with all four of their children!! And my mom had two "surprise" babies (myself included) so I come from a very fertile line of women.
In my first month TTC, I tracked my ovulation, recorded every little symptom, did the deed an insane amount our first month, got preseed... Everything you could do to try to get pregnant and failed. I was heart broken. I had my heart set on getting pregnant instantly.. I know not very realistic.
December we tried again... Thinking November was just a fluke.. Nope. Got my period on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. Merry Christmas to me..
So, it's been 6 months. I've ovulated every month, my periods are consistent, my husband and I are both young and healthy with no major health issues...
WHATS WRONG???
