Morning 
really need anyone’s help please, if you have been through similar please share. I’m going out of my mind, been trying for 1 year 1 month, I was on contraception about 16 years. Each month my symptoms before ov and af have got worse, but this month is so different. Before af was due I got really bad pain in boobs, bad headache, bloated gassy stomach and the rest but these are new symptoms. My af came a day early but hardly anything for about to days , it’s was pinky and bright then just brown. So I thought this is it I’m not pregnant but then those symptoms as said above have carried on as well as bad taste in my mouth, it’s now 8 days after af and I did a test yesterday and an extremely faint line showed 
but was hardly there I did 3 test to check and the other two were more like shadows and did one this morning which all so is like a shadow but the other tests out the same batch didn’t show a shadow 
could I be pregnant or are these one step tests playing games? I feel pregnant, I’ve got cramps which always normally stop after af, I’m so confused and it’s driving me mad. I know people will say just wait but I’m going out my mind 
any help is welcome good or bad thanks
