I had a question. Well I don't know if I'm pregnant but I been getting all the symptoms as headache, backache, nausea, cravings, bloating, cramping, breast tenderness, sensitive smell, frequency urination and well the question is that I been having so much cramping  especially at night by my uterus also was feeling nausea and Idk if it's normal because I never experiment this before. Last period was on September 16 and was suppose to get my next period on October 16 and I didn't. I had sexual contact on October 1st but not sure about my ovulation date but I had a feeling it was the same day me and my partner did something. Can you please help I'm worried. I took plan B on the 3rd of October but never had symptoms and now that I'm here I feel like the pill didn't work now that I had took the pill 4 weeks ago I started noticing symptoms but what I do know is a week later which was on October 11th I bleed for 4 days but nothing like my period and I didn't feel it until I took my clothe of and saw it and it was brownish and last for 4 hours, later again it was brownish and it stopped till the next day it was still brownish till the middle of the day it got light red and then the last 2 days it was red but not heavy all I used was a pantie liner so I'm so confused can you please help I'm lost. Can I be pregnant? Even if I took plan B plus it says that plan B is only for people not over weight is that true because I'm 210. Also forgot I was having white discharge but wasn't sticky or nothing it was very white and didn't smell.
