am i pregnant

Help, I thought I got off my period two days ago but yesterday after my boyfriend and I had sex I started bleeding again. I thought it was just my period and I wasn’t concerned because I though if I was bleeding I couldn’t be pregnant. Is that the case? This morning I threw up mucus (morning sickness?) and now i’m really sketched please help. BTW after my placebo pills I wasn’t able to take my birth control for two days.
