Ok so first before i sound wierd, I didn't know I was pregnant with dc untill I was 5 months and went to the docs for a different reason (so if hadnt went to talk probs wouldnt have known for longer) i had no feelings or symptoms and was clueless! ever since though anytime i start to feel any way i did when I was pregnant i panic and think I am again wether its feeling sick or my boobs are sore etc 

long story short i'm on the implant was bleeding alot the other month for a few weeks which stopped then i had sex which started the bleeding again for a firther 2/3 weeks with alot of feeling sick and pain like cramps. Docs done a blood test and apart from being anemic (already was) everything was normal, would they have been able to tell if i was pregnant from my bloods regardless of what they tested? The GP also down a quick examination on me and said everything look fine and that was it really.
But over the last maybe week i have been feeling this wierd sick after i eat or think of eating which i remember being like from being pregnant and my mind is going crazy incase i am or could be. I've spent all sorts of money in the past 2 years with tests and was wondering if a doctor would know from what ive said above if i could be? before i go waste more money to see
