I am so confused!

Megan
I was due on my period on the 1st June. I was certain I was pregnant as I bd during my previous fertile week but It came on the 5th but wasn't my usual period I didn't have the headaches and cramps coming up to it and during it. It lasted for three days and since then I have had most of the pregnancy symptoms, i am nauseous and SOOO exhausted literally 24/7. My sense of smell has been crazy my mum was eating a bag of crisps downstairs and I could smell them, I'm starting to have tingly breasts and strange little pains in my legs and arms and starting to have mild cramps that last a couple seconds. I'm just so confused because I had bled at the beginning of the month. Has this happened to anyone else and they did happen to be pregnant ??
