PLEASE READ! I NEED ANSWERS!👇🏻👇🏻👌🏻

Ok so my periods are sooooo irregular it's so crazy. And I've heard that lots of women have had irregular ones and still gotten pregnant but I'm seriously losing hope!!! Has anyone had really crazy periods but still conceived !? My period will be like a whole 4-6 weeks without it and when I get it, it can last like 2-3 weeks. It's soooo long. Long time in between and it also lasts forever. I use ovulation tests and they will read positive but it seems random, and I have sex when I ovulate but still nothing. 🙁😞☹️😔
