How long was your first cycle?

Alison • I`m 29 and my husband is 33. We got married in June, moved to Michigan, and I started a new career as a Food Scientist! We are pregnant with #1! Proposed due date is July 20th 😁
How long was your first cycle after you stopped taking birth control? With BC I had a 28 day cycle. I'm on cycle day 33 right now and still no AF. Tested on CD 30 and got a BFN.. I've been having weird pinching cramps in my pelvic area which are different from my usual pms cramps. I'm confused..
