How would I know if I have a miscarriage or am I just on my period? Let it be known that I take birth control pills everyday at the same time and never miss a day. But my boyfriend and I are very sexually active. On the 26th is my first day of my period but it never came until 3am on the 27th and it was painful. My body ache and cramps was so bad. I was also getting chills and night sweats. It was like I gots ran over by 16 wheeler truck twice. I couldn’t get out of bed because how bad it was. It was a usually bleeding like I was on period but I never experienced any of this before. But today (28th) I felt fine for awhile until I feel nauseated and my body started to ache again (this around 7-8ish am). Then after drinking some water I felt fine. I was at work, by the way. After work, I went to pee and no blood came out (3-4ish pm) nor on my pads. But just now (8:10 pm) I clout of blood just came out. It didn’t look like my “usual” period. So, did I just have a miscarriage or am I tripping?
