Am I pregnant ???

Had period last month on time had sex right before ovulation using Preseed... this month my period is non existent no spotting nothing. Feeling so bloated can barely lay on my stomach to sleep which has never been a problem light headaches mood swings moist ALL THE TIME (TMI) && my nose looks bigger Took two cheap tests around 12/4-12/8 both BFN 😔 just got a new test today. I’m scared to take it plus I wanna do it first thing in the am. I’m 32 years old and my son is 13. Haven’t been pregnant since I had him. Was on IUD 8 years after having him. Been to the regular gyn she says I’m good to go with period I’m ovulating but no BFP Been taking Natures Truth prenatal vitamins for BEFORE DURING &AFTER pregnancy for about 30 days. Could those screw my cycle up? Any Advice ???
