Thoughts?

Sooo just to get this part out of the way I’m 69 days late on my period. I’ve had pregnancy tests but they were negative even from the doctors. I’ve had 4 random days of throwing up, and then feeling better like 5 minutes afterwards. After sex I bleed, but then it stops. Most days I’m spotting but it’s never enough to fill a pad. The last couple of days have been no spotting unless it’s after sex or masturbation. I have an appointment on Monday for this, it’ll be an ultrasound. But I have to say I’m extremely nervous..
