Millinette 30/75

Ever since i started the contraceptive pill I've been feeling quite nauseous to the extent where thinking about certain foods makes me feel sick ? I'm naturally a very paranoid person and i always think 'oh god what if I'm pregnant ' even though I've never had penetrative sex . The last 2 acts I engaged in after my period were done with both of us fully clothed so I know I cannot get pregnant but I still worry anyway because I had a wet patch down their and I'm scared his fluids leaked . Anyone who's on the pill please help ? I've almost been on it 2 weeks , thank you p.s I'm on millinette 30/75. Sorry for tmi but I've been needing to poo alot more and it's more runny than usual accompanied by light cramps and gas
