I went to the er yesterday they gave me one and a half bags of fluids, took blood, gave meds via iv and also i had give blood that week all from the same vein it took her a while to get that vein to bleed and had to push on the vein to make it bleed. now

What's your question: If I understand correctly, you were healthy enough to give/donate blood earlier this week. However, since then, you got sick enough to go to ER where you needed 1 1/2 bags of fluid, presumably due to dehydration which explains why they had difficulty getting into a vein, regardless of whether or not you'd recently donated blood. Hope you're feeling better. Follow up w/your Family Doc.
