So, I used to be irregular. I have PCOS but for the past year I’ve had a regular period. Every month my period comes. If it is late it would be late maybe a day or two but that’s it. So I had my last period was 11/18-11/23. Im trying to start my birth control (Trinessa) but I’m afraid I might actually be pregnant this time. But I have no symptoms other than I want to cry all the time I can’t control it. I had really bad cramps like the day before I was supposed to have my period 12/18 but it never came. I took a test on 12/21 and it said negative. I don’t mind being pregnant. I just don’t want to waste my money or begin taking my birth control on Sunday to find out that I am. Has anyone been pregnant and had this experience? Last time I was pregnant I had a MC. I didn’t know I was pregnant until about 6 weeks. I didn’t have any symptoms at all outside really tender breasts. I haven’t even gotten tender breasts so that’s why I don’t think I would be but I’m unsure. Also if I do start my birth control Sunday will it harm the baby if I later find I am pregnant?
