Help😑

We’ve been TTC since Nov 2017. I get super positive OPKS. We BD on those days surrounding the positive tests. I lay for 5-10 min with hips propped up. We use Preseed sometime, when we have time lol 🙄🤦🏼‍♀️ I had an HSG in May, results were great, tubes are great. I’ve had a successful pregnancy 7 years ago, I’m 35 now. All blood work is great currently. Hubby is on clomid to increase his testosterone levels, they were quite low. He’s started his 3rd month this week. What gives!!!??? How the hell do people get pregnant so easily! Lol We will take any and all advice we can get!
