Normal for getting off the pill

I started my period when I was 13 years old. For years it was quite irregular but as I got older it finally evened itself out and was once every month. Not like clockwork, but I was having a period every 4-5 weeks. I started birth control in January of 2017 and took my last pill on January 21 2018 when my husband and I started TTC. I didn’t have a period in February but started one on March 1st, lasting to March 5th. I started a Clearblue digital ovulation test kit in Mid March just to see if I could track ovulation and literally got 20 flashing smiley faces in a row... testing both am and pm some days. I got so annoyed with it and stopped doing them. AF still has not showed up as of April 29 and I’ve had 5 BFNs. Does this sound normal for getting off birth control? I’m trying to not worry too much yet because I know in the grand scheme of things I’m still new to the TTC world and being off BC. Thanks 😘
