Hi. I am usually super regular and predictable. 28-29 day cycles and have fairly reliable mid cycle ovulation pains (I have one DS who we were fortunate to conceive quickly based on this). I haven't been tracking using temp/opks so I know I can't say for sure. My period is now two days late. I did a free test last Friday morning which I think was 11dpo and it was negative. Over the weekend I had lots of cramping and so I was expecting AF on Monday. Nothing at all and still nothing. This month I switched from folic acid/vit d tablets to Seven Seas Conception Vitamins. I read a bit anecdotally online about some people reporting that they might have extended their cycle a bit (but some of the people had just come off the pill etc. so their cycles were already a bit variable). I haven't tested again but I might test tomorrow morning. I feel like I'm getting my hopes up that I'll get a bfp but also feel like maybe the seven seas has messed up my cycle (and I'm worried that it will take months to get back to normal again!). Has anyone had this experience with seven seas vitamins (the folic acid/vit d tablets did not affect me in this way at all).
