Worried ):

I just switched to Lessina? Lesina? Birth control, this is my second month on it. Me and my boyfriend had unprotected sex about a week after my last period, and that was around the same time i started to work out. Now for the past couple of days I’ve been spotting and cramping like I’m on my period and getting a wave of nausea around the same time every night. I’m not sure if it’s due to egg implantation or because I’m working out when i never have before, but I’m just. Scared. Any ideas?
