Irregular periods

I have a question. Has anyone gotten pregnant with period cycles being as long as 37 days? Lasting 5 days? I’m starting not to be so hopeful with having a baby with my periods being so long. I just joined a month ago and started tracking my ovulation time. My last period was Feb 4th and I’m due for AF March 11th. I’ve had sex the entire week before my ovulation window and the whole ovulation window (week span) Today is March 7th and I’m getting period like cramps with tender breasts. Also have this dull pain in my hip down to my thigh. Anyone experienced this? I just want to know if I’m alone..
