I need help. 6 days ago I would wipe and have pink discharge. That lasted for 3 days then on the fourth and fifth day I had light light blood. Used a liner. And yesterday night abf today I have brown blood. Very very light. I've a very slight cramps. Almost not enough to notice. When I get periods I am very heavy and it lasts 6 days and I normally get really sick. My back would hurt really bad. But now I'm having just little twinges in my tummy and after I eat I feel sick for a little while. 2 days before I started spotting I took amocicillin for a sinus infection but for only two days and then I got a yeast infection. Could the spotting be from that? And I'm not suppose to start my period till tomorrow or Sunday. I've never gotten a yeast infection from antibiotics.
