So I have been having some very odd symptoms going and am beginning to wonder more if I'm experiencing rare pregnancy symptoms or something more is going on...

First for over a week I have been having what I think is burning mouth syndrome (BMS) that I thought was caused by a possible vitamin B12 deficiency or my Hashimoto's acting up....the tip of my tongue is numb with a painful pins and needles feeling and my lips are numb. They actually feel like I have a topical pain reliever on them but I have not used any such product. I also have lost all taste (a brownie tastes the same as a chicken or drinks all taste like water). I went to the doctor Wednesday who said "this is an odd presentation" and couldn't find anything wrong besides fluid behind my ears and bags under my eyes which she said could be pushing on a cranial nerve causing the loss of sensation in my tongue but that was unlikely. She is ran some blood test yesterday (CBC, CMP, TSH, T3, T4, sed rate) which I'm still waiting on.

Today I woke up to find a large blood clot that I was not expecting. I have been having dark brownish to bright red discharge all day and it is a similar pattern/color to what I experience my first day of AF, but it is too early for AF. I also have some cramping. My last was Jan 26th and I only stopped breastfeeding about a month ago. I have had a history of irregular periods (as often as every two weeks)...my last AF was only my 5th since my April '11 LO. First 3 were to the day of each other (20th of month), the 4th was 4 days later (24th) and the last one was 2 days later (26th), but that one was irregular in that my flow would come and go for over a weeks. I did take a HPT yesterday which was obviously negative. The thought of implantation bleeding has crossed my mind, but it seems so mug like my regular AF and heavier from what I see mentioned as implantation bleeding.

I have been having diarrhea on and off today as well. I should also meantion that I do have a thyroid nodule that they are "watching" (basically waiting for it to grow enough to biopsy. It was deemed indeterminate on last u/s) and am scheduled to have a repeat u/s Monday and an endo follow-up the following week.

Basically has anyone experienced the tongue/lips issue during pregnancy and does the bleeding sound like it could be implantation? Do you think my thyroid is causing problems and/or I'm stressed that my nodule grew or my cycle is off from stopping nursing? (ugh a lot of options lol and sorry for the long post!).
