Could I be pregnant or is it just my PCOS? I was diagnosed with PCOS about 2 years ago. I have been taking cyclic progesterone for three cycles/months. Also started taking vitamin d and b 12. Unsure wether I ovulated or not. My period came on time but it was extremely light started as brown spotting and went on to pink spotting for four days on day five I had red blood only after sex it ended on day 6 went back to spotting. It was a day late. Prior to bleeding I had strange cramps I never cramp before cycle. After bleeding started I only had cramps on day 1. I usually cramp on days 2 and 3 that's also when period is heaviest. I have been constipated which is unusual. Two days after this strange cycle I started having nausea. Ever since the start of the nausea I become nauseated after eating lunch that doesn't go away until I sleep and it turns to hunger then back to nausea. A never ending cycle. The other thing is sensitivity to smell. And I'm emotionally more sensitive. Could I be pregnant or is this my PCOS or just a strange period? Also been bloated.
