Firstly 3/4 of the things you are saying are not signs of pregnancy.

I never had red nipples, or headaches, or cramping, bleeding gums. Your ligaments wont stretch untill about 3 or four months even then its such a small amount they wont be stretching that much untill later

You must have had a weird first pregnancy to get all those bizarre symptoms and especially if your less than a month pregnant.... quite bizarre

Most common first symptoms are missing period, sore and swollen breasts, not red liek you are saying, and nausia, sometimes flu.... headaches etc start allot later and many women don't even get them

Just go and get an HCG blood test at the doctors then you can stop wondering.. Also I have never had these symptoms from the pill either and I have been on almost every pill you can think of... apart from the late period that can happen when you come off the pill
