So 3 weeks ago I had unprotected sex right after my last period and he didn’t pull out🙄 I’m on the pill but still worried. My new period is supposed to start today and hasn’t, I’ve been nauseous and I don’t know if this relates but had diarrhea the other morning. My breast are a little sore and I’ve been getting cramps but not like the ones I get on my period. Could I be pregnant? Please only serious help because I’m freaking out
