I need help please! TMI

Kelly 💖 • TTC #2
Okay, long story short. I basically missed AF for febuary. February 28th I started spotting.. very light, so light I didn't even need to wear a pad.. since then I haven't stopped bleeding.. the last three days have been pretty heavy. So I've been bleeding for 11 days now. All BFNs.
I had blood work done, my FSH levels were low. And I have an ultrasound next week, to see what's going on.
I've been having mild pains on and off near my pelvic area. (Different than cramps)
Can anyone give me some insight, has this happen to you? Thank you. I feel hopeless, my husband and I have been TTC.. and I feel like nothing's going right at the moment.
