Cervical mucus question

Heather

So my dumb brain cannot comprehend. Lol. Sorry. My CM never seems to look like egg whites. Its always either watery or creamy. And my cycles are irregular, lasting between 33-45 days. How can I tell when I ovulate? I tried the ovulation tests from walmart and they never seemed to be positive or anything. We desperately want our boy (2 girls already) and I would love to get pregnant by our anniversary. I stopped bbt and using pregnancy tests because I thought for sure each month would be our month and I just got so tired of seeing BFN. It was breaking my heart. I want our son so badlyb my heart hurts. Help!
