Confused and worried

Hello Just want to ask po if my same experience sa akin. Last period ko po is February 19 , I had sexual contact with my boyfriend march 11 and 16 (unprotected at hindi withdrawal) kasi we want to have a baby. Pero nung march 26-29 I bled and heavy po sya. But April 20 i noticed my tummy is getting bigger, and marami na kong signs and symptoms. Nausea and vomiting, morning and night sickness , pangagalay at pag sakit ng likod ,binti hanggang paa. Hindi ako makatulog ng maayos almost two weeks na. Minsan mainit katawan ko at irritable , nag heheart burn din po. Meron po ba ganun? na akala ko normal period lng kasi heavy pero implantation na pala? buntis po ba kaya ako? sana my maka sagot. Di pa ako ng Pt. And if ever na buntis ako I'm 9 weeks pregnant but I'm not sure.
