Faint Line...two days ago turned positive this morning! ! Still nervous because I have been bleeding..

I had a super faint line two days ago and I am thrilled to see a darker second line!! I'm nervous because I had a miscarriage in September and for the past week and I have bleed everytime I have had sex? I spotted a little but I bleed bright red when we have intercourse. It stops afterwards. I am just so nervous. I don't was repeat of last time :(.. I won't be able to see a doctor till next week because of the holiday so I don't know what to make of this?

Also Vitex? can take while pregnant. Will help prevent miscarriage? Increase progesterone levels? Any advice I would appreciate..Happy New Year
