not possible right ?

so almost 3 weeks ago i had a (suspected) chemical. i was getting faint positives had all the symptoms but started bleeding a week later after my missed period (my period ALWAYS comes on time. i’ve had a miscarriage before so i definitely know my pregnancy symptoms. anyways ever since then even after the bleeding stopped i kept getting cramps. they’re more light and random now but still happen. well today i woke up and my nipples are superrrr sore which has only ever happened when i was pregnant. as well as i’ve been having severeeee nausea the past couple days and also head aches. it’s impossible to have already ovulated right ? and even if i did there’s no way i would already have pregnancy symptoms? the app estimates my period to be 10 days away. i only have a dollar store test left and a FR digital and i don’t wanna waste them but also feel so impatient 😩
