TTC with irregular periods (first months trying and I'm out)

I know it's too soon to get all depressed but I'm depressed that I continue to get BFN. This is my first month trying and I've always had irregular periods so I'm pretty stressed. I don't even wanna know how long it'll take me to conceive. I'm TTC my first little pumpkin 💕 well Next month we try again...what can I do to help the process
