Period came early but I think I may be pregnant..

Me & my boyfriend have now been trying for about a month now to get pregnant. I've been on here tracking, took the tests when glow said to... both tests were negative (my first pregnancies never had a positive test until 1-2 months preg) my period came 2 days early & seems like its goong to end sooner. My boyfriend brought pizza by me & i almost threw up than woke up in pain & very nautious. Could I possibly be pregnant?
