Experiences please!!🙏

I just found out I'm pregnant today approximately 3/4 weeks. I caught my sons cold and have been taking halls and cold medicine for 2 1/2 days now. My OB office says I should be fine as long as I stop taking the meds but I just want other experiences to help ease the nerves. I'm high risk until my 6 week ultrasound due to a past ectopic pregnancy, and I've had 2 miscarriages so I'm super nervous but trying to stay positive.
