A few weeks ago , me and my partner had unprotected sex and I took the morning after pill . Recently we had unprotected sec but he didn’t cum in me therefore I didn’t take the pill . Because my periods if always due at the last days of the month , Today I found brown discharge on my panties and I dunno if  I’m pregnant or it’s just a side effect for my periods . and I’m having this terrible headache I dunno if it’s coz I’m stressed or ,
