Okay all, as some of you know hubby and I are on month #18 on trying for our first baby. This is the first month that I honestly have not felt stressed out and stretched thin. I'm now 2.5 weeks late, with 2 negative HPTs. The past couple of weeks I have been extremely fatigued and have had morning and night nausea, super sore and enlarged breasts, and have had to pee like every 20 minutes. (Hence why I have taken two tests) But the past couple of days I've had a weird tightness and almost pressure in my lower abdomen where my uterus would be. It's not cramping at all, but just kinda feels like that area is a little swollen/bloated. Has anyone felt this same thing in early pregnancy? I have called my doctor and they say as long as I'm not in pain and that it's not uncomfortable that I don't need to be concerned (could be gas, pulled muscle, tweaked nerve.) I'm just wondering if it is possible that I'm super early in a pregnancy and that's just my body's reaction? Test again in a few days, or asked to be seen?
