Hello. I normally have regular periods. Around every 28-30 days. I have been nauseous day and night, smell sensitivities, lower back aches, headaches, milky white discharge forthe last two days, fullness in my abdomen, fatigue, breast tenderness and they feel swollen, frequent urination, and just started having some constipation as well. I had my last child 4 years ago and my doctor cut a small portion of my tubes so I am wondering if I could be pregnant. I havent taken a home pregnancy test yet. What do you think?
