Its been over 110 days since Ive last had a period

With 20+ negative HPTs and 1 Negative blood test- Im stumped

I stopper birth control in September and had a 5 week period but after that- Ive had nothing

End of December, I started to try for a baby. Still all negatives

So the question.. where can I go to see a doctor ASAP? ER?

All the gynocologists in my area are booked for 4 months out and Im starting to get concerned

Im overly emotional

Losing hair

Dropped below 100lb and I usually stay between 105-115lb

Im having cramps

Migraines everyday

Its driving me nuts!
