When did you start ttc?

I agree with PP, there are plenty of apps available that track your period (I use Clue) and can help alert you to your few fertile days each month. Essentially, you'd be practicing natural family planning - which can be a great option when hormonal BC and condoms are not feasible.

I stopped with the pill because it was making me crazy among other things. I also will not try any other form so I recently started the pull out method lol. I am not allergic to condoms but most of them irritate me. We are not getting married until next year so we are trying to be super careful. I don't really have any advice except just stop doing all forms of BC. It sounds like you both are on the same page so I think you will be ok.

I don't have any advice on the pull and pray method since we're a same sex couple, but I have problems with irregular periods and wanted to give some unwarranted advice lol. I suffer from PCOS and have always had ridiculous periods. They would be 30-40 days long, then none for months, maybe spotting in between, literally couldn't have been more random. I started taking Balance, a supplement by Alani Nu and it's worked wonders for me. Not only has it regulated my cycles, but it's helped with other side effects of my hormonal imbalance as well; my skin has cleared up, my hair is growing much faster, my metabolism seems to have regulated. I could go on, but I know that I sound like a paid spokesperson, which I'm not, I'm just really passionate because it's seriously a miracle to find something that helps. Definitely check out their reviews!

It is expensive, but have you thought about the Ava bracelet? It is for TTC but it tracks your ovulation and would let you know what days you were ovulating and you could use those days however you wanted to depending on if you were TTC or TTA(trying to avoid).

First of all, I'd definitely discuss your fertility and your cycle with your OBGYN and plan a pre-conception visit! They are super informative and really helpful, even if you are trying to prevent pregnancy! But also, they can help discuss how likely you are to get pregnant, because if your periods are super irregular, its likely that your fertile window isn't regular either. I'd probably buy some fertility strips off of Amazon, and start using those daily until you can track your ovulation. They are super cheap and easy to use, and after you've used them for a while it'll be easier to know when you are ovulating so you can avoid pregnancy. Because your cycles are so irregular, those apps will be more annoying than helpful and they probably won't do much good for you right now. Definitely invest a little money into fertility strips and start there!

This is a super helpful book and I would absolutely recommend this as well.

There are other methods, e.g., implants, that can give you long-term but reversible protection. However, if you're not too concerned about failure rates, natural family planning can work. However, with irregular periods, you need to be checking for ovulation (there are several methods), rather than just using the calendar.
