please give me some advice

Kerr
Af was due 5 days ago, no sign at all of her appearing. But Have I had early pregnancy symptoms? Feeling sick a lot, had my first 3 migraines this month (never had one before in my whole life) had the odd sharp pain in my nipple and a few twinges and bloating in my lower stomach but I don't know what to think, don't want to get my hopes up! Used a cheap test on the day that AF was due and got a bfn!!! Anyone anything to help me?
