Ok so should I go to the doctor or am I jealous

So I posted on here before about feeling pregnant or having symptoms and still not end up being pregnant. So now my symptoms have increased. I still have been getting my period every month but the dates switched from the first week of the month to the second week of the month. My symptoms are nausea, fatigue, back pain, acne, increase appetite, swollen feet, bleeding teeth, swollen sore breast and itchy nipple and finally skin much much more softer then ever! Now sounds pregnant right? But remember I have full blown periods and has ovulated in the past two months including this one and all of them I started to spot for two days extremely light only see when I whipe. Here is the twist my best friend just found out she is 8wks pregnant I heard of sharing symptoms but this has been happening for like three months and getting worst could we just be that close or am I just over reacting like do I need to go to the doctor or a mental hospital do I secretly want to be pregnant even though I don't want another kid especially right now since my first pregnancy was sooooooo messed up. Oh wait one more twist my boyfriend is my best friend boyfriend best best friend lol yea we are dating best friends lol but he is sleeping all the time like all the time but he does not know about the baby what's going on need help if anything just help me calm down please
