Needing advice ASAP

Samantha • IVF warrior! Infertility for 5 years. 1 miscarriage 8/15/17. 1 embryo that didn’t take 12/17. Last 2 embryos went in and pregnant with Di/Di twins!!!! Rainbow babies due 8/19.

Just got home and felt like I was bleeding. I'm supposed to be 6 weeks tomorrow and I had no sorting up until now. Got pregnant from <a href="">IVF</a>. First pregnancy and freaking out. Can anyone tell me if this is normal or should I be concerned?
