Any Pregnancy chances! Can i get pregn?

After my period s, 7th day i had unproducted sex with my boyfriend, while  having,  he pulled out his sexual organ and he himself masturbated himself and ejaculated on my stomach, he didn't ejaculated his sperm inside my vagina! To be in safer side after 9hr i took ipill tablet, After 5 days i started to bleed and it lasted for7 days! *(Fed 11th) was my date but after taking i pill tablet again in same month( 23rd Fed) i started to bleed and it lasted for days, Now this march i though i might get periods on 11th march but i missed that date, again i am waiting for march 23rd, but no symptoms of getting period s for tomorrow ! I haven't done pregnancy test yet due to corana effect here everything is closed. But yesterday i googling i found that if we mix morning urin to salt then if urin turn s to milky white then it is positive, if salt doesn't dilute s in urin then is negative !!! Is this method really ture. i tried it but my result was +ve. Please anybody confirm me can i get pregn
