I'd definitely advise getting ovulation tests if there is any sort of question mark regarding ovulation and your cycles
Unless you religiously have sex every other day throughout your cycle, then they will help you to make sure you are doing it at the right time. I know a few women that went from ttc for AGES and then trying OPKs for a couple of cycles and they get pregnant.
Plus, if you are getting an LH surge it's a good indicator that your hormone balance is pretty good. You need good follicle growth to get a surge.
And, you can also know when your next period can be expected
ClearBlue Fertility Monitors are well worth the money imo, but you can get cheapies.
Honestly, i'm not on commision
Keep a diary of all your dates too.
It must be so scary knowing that you have a tumour somewhere - any plans to remove it? How did they finally diagnose it? Did you have to go through all the usual fertility tests and ultrasounds and then they finally did an MRI scan or something?
Sorry for all the questions. I crave knowledge
I know it's harder to cope with something when you can't find anyone in the same boat! I'm there myself. Apparently my situation is uncommon but not unheard of - can i find anyone else in the same boat? Nope.
