Opinions please

I did three different test. Two of them had faint positives and one was obviously negative. I didn’t have a period at all during June. I don’t really have many symptoms. I have been extremely tired and I’ve had lower back pain, an addiction to salt, frequent urination, and it’s like I can’t ever have enough to drink. I’m not under any stress nor has any diet/schedule changed. My boyfriend and I have a lot of unprotected sex but we try to pull out or do something different during my fertile window except we kinda messes up this month. My fertile window was the middle of the month during June. Should I consider pregnancy or is my period just skipping out on me for other reasons? would it be to early to tell? Should I test again or just let it go
