Ttc 10 months no positive feeling overwhelmed

Ashley • Married. 24 years old work in a dental office. Trying to start a family with my awesome husband!
Husband and I have been ttc for 10 months now each nothing has been getting harder and harder! The week before af comes I get very stressed! Then she shows her ugly face. Trying not to add a bunch of stuff to conceiving husband is very old fashioned! I just don't know what to do I keep feeling it's something wrong with me. Any advice from people who took a little longer to concieve?!
