So this month I had my period on the 4th which lasted around 3 days. The 2nd day being quite heavy. I'm currently ttc. This is the 2nd month of me being off the pill (lucette) my period came bang on (30 day cycle) as I had a withdrawal bleed on the 4th of September. Baring in mind that the week before I had my 7 day break and only took 3 pills out of starting a new pack. Before I was on contraception my cycle was 28 days and my period lasted 5 days. For the past 3 days I've had awful cramps and lower back pain. Yesterday it felt like my back was splitting on two. So I can only put this down to ovulation pain. The thing is on Sunday I was extremely exhausted. I was weak. In and out of sleep all day and felt like I hadnt had any sleep at all. Yesterday I bought a cb ovulation kit. The one that gives you your 4 most fertile days. I tested yesterday and got a circle which means low fertility. I tested again this morning and got the same. I just wondered why it says low fertility if I were having those cramps when in reality I could have been ovulating. By looking at a calender this should be my fertile week with me releasing an egg on the 20th. Does anyone know what this means or experienced this. Is my body not ovulating due to me being of the pill for the 2nd month? I'm just really really confused and wouldn't mind someone to talk to who may have had this before. I already have a daughter who's 7 and me and my partner are so ready for baby number 2. Today I feel great.
