Worried!!

Hey ladies, this is my first time doing this so please bare with me.. lol

The way that I found out I was pregnant was when I seen I was spotting, took a home pregnancy test and came out positive. Still spotting me and my husband were worried so we went to the ER just to keep things on the safe side. They did blood work, urine test, and an ultrasound all coming back to tell me "They THINK I could have possibly had another miscarriage" (This is my second pregnancy, first pregnancy I was pregnant with twins and sadly I miscarried.) 💔 So the Dr. there told me to go home, without any paperwork given or anything. So my husband seen how this second "Miscarrige" got to me, he told me we should get a second opinion, so we did. My new OBGYN did blood test, and ultrasounds and came out to be I was still pregnant and still spotting. He said my hormone level was going up and everything looked fine.. A week later my spotting stopped, now this is were I'm worried and most of all scared! I'm spotting again, went from light pink to a bright red. This is the first time I spot twice. I called my OBGYN and the lady at the front desk said from what she hears it doesn't seem as if I'm having a miscarriage, she said to drink lots of water, and rest. She also said I might be a bit delicate in the vaginal area, to head to the ER if my bleeding starts to become like a period flow. Is it normal to spot twice? Please help..
