So I was suppose to ovulate October 3rd I had sex multiple time with my partner on October 2nd and October 4th and a few times throughout the month. According to glow my period should have came on , on the 17th but it didn't and switch to the 20th, it came the 20th. Throughout this whole month I been feeling horrible. I'm nauseous all day everyday , stomach cramping , headaches, going to the bathroom more frequently, gassy, and I just spit up last night . I did take a digital test that reads pregnant and not pregnant a few days before my period was to come on the 17th should I take another test even though my period is on?
