The issue is that during my second natural period I was floored with a cold. Then during my third natural period I picked up another cold, although not as bad as the month previous. I'm now in the midst of my fourth natural period and I have yet another cold which feels as bad as the first one I picked up. Admittedly my stress levels have been higher due to completing my university degree this month. I have also put on around 20lbs in about eight months and so my BMI is sitting at around 30, which is something I'm currently working on. Is the fact I'm picking up colds during my period every month a coincidence? I'm actually considering going back on the pill if it will prevent this happening for a fourth month. I work full-time and cannot afford time off work, alongside the general inconvenience of becoming unwell.
Information/advice/similar experiences would be most welcome, thank you.
