My stomachs been hurting since I drank my Starbucks yesterday before going to the park and I just thought I’d feel better after some sleep, but it still hurts like hell. With the way this hurts, it seriously reminds me of when I was pregnant (around maybe 2 months) where I felt like throwing up and sleeping for maybe what felt like 10 minutes and waking up every 2 hours cause of how bad my stomach was hurting. It ended up with me going to the hospital to see what was wrong, but apparently there was nothing in the tests they did. No I can’t be pregnant. I’ve also already had my period and am waiting for my next one to come in about 2 more weeks. I just hope my stomach stops hurting cause this totally sucks.
