I feel pregnant but had 1 day of AF plus neg hpt

ttc33

So long story short...I just feel pregnant this month! I have been Insanely emotional, super gassy & nauseas. I had a few red clots but not much of an actual period...only used one tampon and nothing else since. I’ve had awful stomach pains/cramps. I took this test today and kinda feel like I see a SUPER faint line... I’m pretty sure it’s the indent. I’ll take another in a few days. Has anyone ever had this happen and actually been pregnant?
