Ovulation cramps while on the rod

Hi I recently got the rod after having my first baby. More then a week ago I got ovulation cramps as I would get when I wasn’t on it. Now today and yesterday I am feeling very tired even with sleeping a full nights sleep both night. Smells of food is stronger then before and I keep feeling the need to vomit plus I have gas. I am worried as this is what happened last time I got pregnant around the same time. I just want to know if it’s possible for me to be pregnant as I really do not want to be as my body did not handle pregnancy very well last time. I miscarried one twin had many bleeds and had my daughter at 26 weeks she is (6 months now and the most happy baby) but I can not handle the thought of going through all that again and possibly losing another baby. So I need to know if that’s even possible to ease my anxiety. Thank you for reading 😀
