I started running again last week at 5 weeks PP. I ran my first run 1.5 miles slow, slow, SLOW! I ran 2 more times last week 2 miles then 2.5 miles. Every time I start running I have some pain in my lower abdomen/I guess my uterus? It goes away less than 2 minutes into my run so I haven't thought much of it. Today I ran my first 5k. Again, it hurt at the start but went away. Now, 3 hours later, my lower abdomen is hurting - A LOT. Has anyone else experienced something like this when getting back into your regular routine? Should I worry about the pain or just keep taking it slow?
