When should I test??

I'm tired of getting negatives. Last month I guess I just missed my peak and was obsessing about testing. This month I'm not trying to get my hopes up but I swear I had implantation bleeding yesterday.

That would be around the time it would happen right?

I've been feeling bloated, little twinges/ pulling and some cramping. My boobs hurt so bad and feel really heavy. I never really paid attention to pms symptoms before this tho so maybe I'm just overthinking it? Pls help me have some peace of mind! 😕
