TTC - SMEP

We are in month 9 after this cycle of TTC baby number 2. I feel like a newbie at this all over again. Has anyone had success with the SMEP? Or are there other routes you have taken? I do track with opk, I do not do bbt, even though I’ve heard that’s most accurate...it’s just not for me. I like the opk, they’re fun to me 😂🤦🏼‍♀️ (weird, I know)

Any advice is appreciative, we’re both on the verge of turning 32! Our first son is now 2.5...which is why I’m getting antsy at this point...I want them close in age! I was an oopsie baby, my sister and I are 10 years apart, my brothers and I are 12 and 14 years apart! So you can see why I would love for a closeness in age 😬 I love my siblings, we are all super super close now that I’m older, but growing up was a wild ride 😂
