Hi. I'm 20 years old and i've been trying to conceive for 6 months. I was supposed to get my period on the 19th and it appeared to be right on time but it was dark brown like it should be at the end and there wasn't a lot. All of my tampons have been perfectly clean since the first one. My fiance said that he noticed a pinkish look during sex the day before my period was due. Could I be pregnant???
