For a little while now - 2-3 weeks, maybe longer - I've been getting a sensitive feeling in my abdominal area. It doesn't feel like a cramp or something very painful. It's not necessarily a deep pain, it's often more of sensitive sensation in my skin. Sometimes I feel the same but deeper. It has been largely focused on my left side, with occasionally being more central. Sometimes I get a fluttering/quickening feeling, which I had put down to likely being wind, still always on the left.
At first I thought it might be ovulation, as when I first noticed it I was around my usual ovulation time. I've always had lots of symptoms with my periods (pah) and I do get mittelschmerz, but this feels a bit different from usual. Considering how long it has been going on I figured it couldn't just be mittelschmerz or menstrual pain, as they've both been and gone and the same feeling has continued. Today I felt a little 'pop' in that area and then the sensitivity increased.
Alongside this, I've noticed that I've had an upset stomach a couple of times (on one occasion I got very bad cramping and diarrhoea 
) and a bloated feeling during this period. However, I don't look bloated. I have also been getting increased lower back pain and headaches, again not severe but enough to be annoying and noticeable.
I have an appointment booked with the GP for 2 weeks' time for a separate issue but I could raise this with him too, however as it's been going on for a couple of weeks it's starting to make me 
and I was wondering if anyone else had experienced the same? Please don't tell me I just get to experience PMS all the time 
Fwiw I have hypothyroidism and recently had bloods done for thyroid function and iron, with all coming out fine. I regularly get these checked along with B12 and folic acid, so far everything seems to be managed on that front.
