I usually have 28-30 day cycles with spotting 1-2 days prior. This cycle, I was taking bbt and at first it predicted ovulation on cycle day 13 however I had a fever towards the end of my cycle and I am not sure if that effected by bbt but it started saying I ovulated on cycle day 18. Now if that’s true, I should start my period tommrow which would by cycle day 35 which has never happened in the last three years. If I am going by my usual , I would currently be 3 days late. I am having mild crampy/tickling feeling and I feel mild nausea throughout the day but not so much to make me vomit. I have symptom spotted in the past and after TTC (trying to conceive) for 9 months I really don’t want to get my hopes up. I have been using easy at home hcg tests all are negative. Every time I feel my period has come, it’s just clear discharge. Has anyone experienced this? I thought tests can give you a faint line at 3 days late unless obviously I ovulated late :/. I’m not sure, would really appreciate some input.
