This is the first time ive been on antibiotics ever. And im only 6 weeks pregnant according to my last period. What are some things to look out for if something is wrong ? This morning i woke up with a bunch of discharge slightly off in color. It looks like maybe a bit of blood was mixed in. At what point is spotting a concern? Over a certain amount ? I know i spotted occasionally on my first 2 pregnancies, but i hadnt been on antibiotics or had an infection. I just want to make sure this little babe is okay.
