Yes the ProoV multi hormone strips can be really helpful for figuring out hormones!
With my first son, it took just about a year after removing my IUD to get pregnant but once I did the first time ( resulted in termination ) I got pregnant 9 months later in October ( I was using protection during those 9 months ) after my son was born, I had an IUD again & when I took it out to try for the second, I got pregnant literally a month after getting it removed. Resulted in a miscarriage & then got pregnant with my rainbow baby in July. I believe it just all depends on you & dads sex health like his sperm & your eggs & if you’re tracking your ovulation correctly. Don’t get discouraged 🥰
I don’t have experience with the IUD, I used premom app and strips for my June ‘21 babe and my September ‘23 baby. But it took 9/10 months to conceive the second time even though we had a similar experience as you first time around. I finally tried the ProoV multi hormone strips as it seemed I wasn’t ovulating or at least not getting a very dark LH line. Turns out I was ovulating like 2 weeks later than the Premom app thought I was. Got pregnant the first month using those strips! Highly recommend
