rainbow baby and terrified

so I am 8 weeks and 4 days pregnant with my rainbow baby and had some slight bleeding in week 5 but was told everything is fine everything is great just a small tear that will resolve itself well then I got told I had a UTI and a yeast infection (I swear y'all I'm not dirty) and I got super scared I took the monistat 7 and nothing and I took the UTI pills and they worked but every now and again I get super sharp stabbing electric feeling pain in my vagina abdominal area I'm so scared and my doctor doesn't tell me anything
