Getting anxious. Advice??

Starting to get really anxious. I’m on the pill and I take it every day but some days I’m late by 2-4 hours. My boyfriend and I always use protection when we have sex.

Last week was the second week of my BC pill pack and I started spotting during the middle of the week. My boobs are super sore and sensitive. My stomach just feels heavy and sometimes it feels like I can feel little flutters. Do these sound like pregnancy symptoms?? I plan to take a test next week when I expect my period but I just need insight now
