I calculate 13.3 weeks per trimester, and I am not sad to say goodbye to the 1st tri for the last time. My energy levels and nausea are definitely WAY improved. I have also been offered additional FREE ultrasounds because the free clinic is doing training. I'll have one this Thursday night, and they aren't allowed to give any diagnostic information, but there is a very slight chance I might be able to figure out the gender for myself. I know it's early, but I am pretty confident in my u/s evaluation skills. I am eager to find out, so VERY excited!!
