Has anyone experience a heightened sense of anxiety since becoming pregnant?

I was diagnosed with general anxiety, OCD, and depression, which i have been able to keep under control since graduating college in May. I actually stopped taking my medication because my doctor and i thought it would be a good time to see how i would do without medication.

I know that some anxiety is normal, because there are so many changes occurring, but my anxiety has just sky rocketed since I hit my second trimester.

I go to the doctor for my anatomy scan on Tuesday, but i just need to hear from so people till then, so anything helps!!
