BFP but struggling to believe it...

I just wanted to post and ask some advice.

I couldn’t believe my eyes on Saturday when I did a test for no other reason than I felt a bit peculiar and low and behold a v v v faint second line appeared (internet cheapie)!!

So I did another two tests (ic again) on Sunday and there was that line again.... and then I did a first response on Monday and the line was bold as brass. Anyway cut a long story short, 10 positive tests (over four different brands) later (including a clear blue digital which said 2-3 weeks today) and I’m still struggling to believe it.

I’ve spoken to my doctor who has booked me in for 8 weeks for my midwife referral. So she seems to think I’m pregnant!

But here’s the thing - I’m terrified to be happy about it. My period is due any day from yesterday to Thursday (irregular cycles between 23 and 26 days) and I’m worried she’s just going to show.

I’m really worried about a chemical.

Has this happened to anyone else? Has anyone else struggled to get optimistic?

I don’t have one single symptom and I just don’t ‘feel’ pregnant so I’m scared this is just some cruel universe joke!!
