I agree, I notice a lot of topics go unreplied simply because the same question is asked often. Ie - a lot of people ask about pregnancy symptoms - well, in reality you have to look at timing. If its a few days after you had sex, you arent going to feel nauseous. Its probably your nerves knowing what you did. And frequent urination. Im sure some people maybe experienced sooner than others, but from what I understand the pregnancy hormone doesnt start until after a couple weeks after conception (as always someone can correct me if im wrong, ive just been doing a lot of reading since I started trying) and yes, pinkish brownish discharge can be a sign of implantation bleeding. However massive bleeding is a period. Especially if you usually have irregular periods, having this happen later is extremely normal. I will say though that a girl I worked with last year did get her period in the first month she was pregnant, therefore she didnt know until she was about 8 weeks, and experienced morning sickness. So that does happen, I know people say you cant get your period while your pregnant, but to all those with hope I will tell you that I did personally know someone that it happened to. Maybe she always had light periods, therefore ddint notice a difference, and I know it obviously wasnt a period, but it was certainly no different than the ordinary for her.
