Help late period

Rebecca

I had unprotected sex with my boyfriend 1 day before I started ovulation. He came in me but the next day I took a morning after pill and thought it was fine. Exactly 7 days later I had sex again on the last day I was ovulating with no condom but he pulled out and I took another morning after pill. My period is 4 days late and I’ve been having cramps in my lower belly. My stomach keeps growling and I am very gassy. No period but I have white milky discharge every now and than it feels like it’s my period but it’s the white discharge. No other symptoms besides I sleep more deeply and soundly. I took a pregnancy test after being 1 day late and it was negative. I am so worried
