My cycle is 28 days. I had a regular period (5-7 days) August 13th. I had unprotected sex with my boyfriend on the 20th,21st and used film on 22nd. I didn't keep track of the 23rd,24th,25th or 26th. Around the beginning of September I started feeling nausea daily. it went away about 1 week later. I had mild cramps September 7th approximately and for a few days. Nothing like my usual where the aching moves into my thighs and its annoying to walk. The cramps were barely there. i figured my period was due September 10th. On September 11th I had light spotting, just when I wiped and it was pink/brown. On september 12th I had very heavy bleeding. On September 13th, back to light spotting and it ended by the 14th. I feel like my pms has not gone away. Crying over nothing, grumpy and moody still. Also around September 2nd I was extremly constipated, I haven't been constipated in over 10 years. It's been 9 years since I was last pregnant. Should I test? Thanks.
