I had sex on April 9th. I ovulated on April 16th. Can sperm survive for 7 days? My boobs are sore. I'm having slight cramping. My cm is watery and there is more cm than normal. I'm very bloated my back hurts. I had dark red bleeding for two and a half days. The bleeding started 4 days ago and it stopped the day before yesterday. I'm more tired than usual. My period is due in 8 days.
