Ladies Help!!!

Vanessa • Hello Ladies I am a wife and a mother of a 4yr old boy. I am 23 years old, I am also a professional make-up artist. Me and my husband are trying to conceive a babygirl. Any advice ladies?
I have took a pregnancy test 4 days before missed period it came out negative... So I am here thinking I am not pregnant my period is three days late already my boobs are sore Im getting minor cramps in my abdominal area and feel like I have gas. This is my 5th month trying to get pregnant with my husband. Let me know has this ever happen to you? Should I take another pregnancy test or should I wait a couple of more days to see if my period will come? I need advice
