TTC baby #2

I’m trying for baby number 2 right now! I’m still pumping at the moment and I got my period two months ago. It’s been full blown. I was trying last month sorta but wasn’t checking opk or anything. Just having sex randomly after my period for two weeks. I just got my period! 😖 It’s only been one cycle but makes me wonder if it’s gonna take me awhile to get pregnant?!? Ugh…how long did it take you to get preggo with baby number 2? Is it going to be harder for me because I’m still pumping 3 times a day!?! Should I check opk?
