I am 19 years old, but sometimes my periods are still irregular. For the past 4 months, my periods have been coming too early (any where from 24-20 days apart). Last month, my period (which usually lasts 7 days) came on the 6th. It's now the 14th and there's still nothing.
Two weeks ago, I was engaged in sexual activity (but didn't actually have sex). Precum fluid on the guy's boxers came in contact with my (thin) underwear near my opening, but he didn't come and we didn't have sex. I have not engaged in sexual activity other than that since before my last period. However, I'm having some pregnancy-like symptoms. I've been more hungry, my nipples seem a little strange, I'm bloated, I have a bubbly/gassy stomach, and I've been a little emotional. I have no breast tenderness, no increased bathroom usage, and no little pink splotch of blood that I've heard appears on one's underwear in the first week or so. I'm planning on taking a pregnancy test, but I've heard to wait until two weeks after the missed period. Do you think my period's just late, and these symptoms are PMS? Or could I really be pregnant?
