Please dont judge just need some advice.
Well im 7 weeks and 4 days as of today. 
Jun 13th i went to the e.r because i was spotting bright red blood and cramping , seen the babies heart beat and was also told i had BV. I was prescribed flagyl but didnt start taking until today i was scared wanted to look up info on it. But early this morning i had alot of blood when i wiped as well as some stringy thick clots and then it stopped and went to a light pink spotting and my lower back has been hurting and some light cramping, in need of some advice if anyone has had the same situation or close too
