TTC help

So me and my bf have been trying to conceive since April. My period has already come for August before my period my boobs have been feeling like really sore and full like heavy and it's been going on since I got off my period and I usually get my period around the 5th-8th of each month. me and bf had sex lastnight and after sex I immediately started spotting brown and I woke up this morning and it looks like my period has started but it's not do for another week i was fine all day yesterday except my boobs but they have been hurting for weeks already and as soon as I have sex I start spotting and today bleeding like crazy so idk if my period has started or what I think so but we've been ttc so I don't want to think that lol I took a test a couple of weeks ago because of boobs hurting nonstop and it was negative I wanna take one but all I've been getting is negative and plus my period just might be early or it might not idk just paranoid I guess
