TTC Question - Long Read:

So my hubby and I have been trying for 2.5 years for another kiddo. Finally seeing a new OB/Fertility doctor (this is my third one) and we're getting on track to figure out the next steps. I self diagnosed myself with PCOS a little over a year ago, new doc confirms I do have it so she prescribed me on Metformin to help with my levels and to hopefully get my cycle back on track. Been taking it for like 3 months now?

Anyways, I recently went in for a ultrasound down there to check why my periods have been super light when I used to be like stupid heavy. My lining is like 1mm so they asked when my last period was. I told them I spotted on the 1st (this month) and pretty regular on the 2nd and by the third nothing, not even spotting. They want me to do a medicine that is supposed to jump my period and than we start fertility medication but one of the nurses was also possibly suggesting I had implantation bleeding. Like has anyone ever experienced this and can tell me if that sounds like it could be? Would it be too early to take a test?

I know each person is different but I've been an emotional wreck lately on top of feeling nauseous like I wanna throw up which I never usually feel like when it comes to my girl time. Guess I'm more venting and trying to not get my hopes up but at the same time I'm always trying to be hopeful.

Anyways, thanks for reading and happy holidays mommas!
