I need advice!!

So I think I’m being stupid but the more I read the more I think ‘could I be?!’

So I haven’t had sex in like 6 weeks to 2 months (me and my boyfriend aren’t overly regular 😂)

So I’ve had a period and thought nothing of it, not too bad etc. But the last 2 day my boobs have been sooooo sore.. I don’t even get sore boobs on my period so this is odd for me. Also I was having some cramps like a was gona come on the other day and that was 7 days before my ‘next’ period was due. They went away and haven’t been back since. Also I’ve started to notice my gums really hurt when I brush my teeth. I’ve said to my boyfriend a few times ‘if we’d of had sex I would be convinced I was pregnant my boobs hurt so much’ I know you’ll say take a test but I don’t wanna waste money/time if it’s ridiculous! What yall think?
