I recently (around 3 months ago) stopped using the birth control pill. I noticed that my last 2 periods both came around 2-3 days late so decided to really take notice of when my next period arrived to see if I maybe have a 30 day cycle instead of the average 28 (while on the pill I had a very regular 28 day cycle). Anyway I am now on day 33. I have been having cramps since day 27. I usually start having cramps the day before my period so expected it to arrive but it so far hasn't. I decided to quickly look up what might cause cramps but no period, and pregnancy came up quite a lot. I had already ruled this out as me and my boyfriend have been using condoms but I suppose they aren't always 100% effective. Anyway while skimming the results I realised another early sign of pregnancy is back pain which I have been suffering with for the past 2 weeks. I work as a nanny and so constantly bend down to pick babies up so I put the back pain down to that but the realisation suddenly hit me that it may be something else.
Is there anything else that it could be? Does pregnancy seem the likely answer?
Any help would be much appreciated.
