Cramps !!!????

Melodie • Baby #1 is 18 months... TTC#1= PREG at my second round of clomid. Now PREG with baby #2. First month we tried, no medication. Due date= nov.2018 ❤️ PCOS+MTHFR+FVLeiden homozygous. 11 years with my husband. 28M-28F
Im 11dpo...yesterday and today I had cramps Ive never experienced before. Feels like period cramps but worst than usual. What do you think it means? Too much stimulation of the ovaries, BFP coming soon? Af is suppose to come in 4 days and I didnt have that symptom while on my first clomid round....only ovulation pain around my ovulation.
