Does it take longer to TTC 2nd child than the 1st one?

Ada

Our daughter is almost 2.5 years old now. We have been ttc baby #2 for 5 months and still no luck. I have irregular period. I downloaded multiple apps and have been taking ovulation tests like crazy... But still no luck yet.. I remember when we ttc the first time 3 years ago . I didn’t do any of those and I was pregnant on the first month of cacual trying. Then I had a chemical pregancy. The very next month I got pregnant again. Feel it was so easy on our first one... We just turned 30 this year..I don’t think our age is an issue. But it is just getting really frustrating..
