Me

okay here's the situation my period is always on time I've never had a problem with that I have hyperthyroidism but it doesn't affect my menstrual cycle. so here's my dilemma my period was supposed to start on the 13th of December it started on the 8th of December which is not a problem 5 days early 6 days early not a problem but when my period started I only spotted the first day the second day barely anything I was just waiting for it to get heavier but nothing third day spotted again. fast forward to the 13th when my original af was supposed to be due... woke up felt like I was coming on my af I went to wipe and I had a brown discharge put a tampon on thought it was weird to have another period but was like ok yet nothing else came for the rest of the day nothing else came in fact until today the 18th I went out last night I had drinks with some friends getting ready for Christmas and I woke up this morning spotted when I wiped nothing else for the rest of the day I have light cramping now here is my dilemma I'm 42 I'll be 43 in February so I'm wondering am I going through menopause is this menopause or could there be a possibility I may be pregnant...any advice besides take a test is greatly appreciated the only reason I will not take a test is because that is just so emotionally draining and I'd rather wait until my next period is due... I'm just wondering if it sounds like menopause I've been Googling it all day
