Dollar store test

Sooo I heard dollar store tests can’t test early ???

Is this true ?? I only ask because I swear i might be pregnant !

Here’s why ...

I stopped birth control the 11th (Thur) started withdrawl bleed Sunday - bled for 11days I DID NOT KNOW YOU COULD OVULATE DURING WITHDRAWL BLEED 🤦🏻‍♀️🤦🏻‍♀️ we been going at it every other day damn near !

My glow said I should ovulate this week / negative tests ! I’m thinking because glow took the bleed as a period when it wasn’t !

I think i May have already ovulated because the past 3 days my boobs have been so tingly and swollen ! Almost sore but mainly my nipples and some cramps here and there . I always get cramps with period but never tender breast or nipples . I have some discharge too ! But I also think i May have developed a yeast infection ! Dollar store test says negative tho ... but again it’s only been 3 weeks since I stopped my birth control soooo if I ovulated the week after i would of only conceived 2 weeks ago maybe one !!! So would dollar store one not pick it up ??? Should I buy a early detection ??? Any insight is greatly appreciated!
