The last couple days my legs have been so sore. Well today since I'm wearing shorts I noticed a small lump on my putter calf part of my leg (only noticeable when I'm flexing. I'm all freaked out. My husband said to wait until tomorrow to see if it gets worse. The lump itself does not hurt, my legs just feel heavy and tired. But I busted butt around my house all day yesterday , followed by an intense love making session with my hubby. I was exhausted to say the least. I'm just worried about a blood clot. I'm 21 weeks tomorrow. Any thoughts??
