My highest ovulation was thursday. My BBT was 99 with pelvic pain (baby dust). After that my BBT a range 98- 98.20. Yesterday I woke up sick, headache dizzy nausea and light cramps/pelvic and slept all day. I've woke up today the same, headache light cramps/pelvic and 98.20 BBT. Last month I had a chemical pregnancy. I need advice. I don't start til September between 5-9 (my app switch the dates). What do you think?
