My period is normally normal for the most part but last month I had a little scare. Two weeks after going unprotected my flow came a little late about 3 to 4 days late. It started with light spotting that turned pink and disappeared in toilet water to two days of medium spotting. Now it is the second of July and I'm still waiting for my flow. It normally comes on the 28th. Last month when I had the scare I took two pregnancy tests which both turned out negative. Is there something wrong? Or what do you think? Last week I was bloated and having the normal PMS issues with emotions and tender breasts, etc but for the most part I'm feeling fine. Soooo has anyone experienced this or what do you think? We had a female visitor for about a month so I've been assuming that my flow is changing because of that, but I just dont know.
