We had unprotected sex the day before my last period which started the 15th April but period was 4 days early and lighter than usual but lasted 5-6 days.. Then day 15 of my cycle for the first time ever I had pinkish brown spotting a bit of pink in pantys and some brown in toilet that lasted as only spotting when I wiped after that for 24 hours. That was on the 1st may .. Now on a normal Cycle 28 day for me but last period was 24 day cycle.. My period is now 7 days late and i have been gassy and bloated for about a week and back twinges mid and lower back , my stomach is so bubbly its like they are popping in there like popcorn.. constipated and frequenting the toilet more often, I am hoping its just a strange period coming , I'm not ready for a 3 rd child right now.. Hubby can't wait to have another and is telling me it will all be ok. I only had a c section 11 months ago so fingers crossed I'm not pregnant. Doing another test in the morning.
