Anyone have weird experiences when getting off the pill?

Brooke
I used to have a fairly irregular cycle. I'd range anywhere from 19 days to 46 days, so I primarily got on birth control to regulate my cycle, which is what it did for 8 years. Loved it. 
I'm now married and my husband and I are open to starting a family, so we pulled the goalie about three months ago. My first couple of periods were normalish, but my last one…well, I didn't even know if it was actually my period or just spotting, it was so different. I knew to expect some adjustment from the hormones, but my body's doing weird stuff and it's kind of freaking me out. I know I'm not pregnant. 
Anyone else have similar experiences or weird adjustments when getting off of birth control?
