So I've been on Previfem what is now about to be four months. My boyfriend and I had sex the day my period tracker said I was starting to ovulate. I'm scared because I've been bloated? and getting slightly nauseous and then it'll pass. Like I may go to sleep with a belly and wake up with a flat tummy. I don't feel pregnant and the negative pregnancy tests give me some kind of light to this. I'm guess I'm just needing reassurance on this and to understand for future reference.
